Just like the goods of today, thermal imaging thermometers are also on the rise, though they are still rather expensive. The temperature range of these devices is up to 1,000°F, which means they are more suitable for use in industrial settings than in your kitchen. One of the most notable thermometers is the Extech EX100, which is widely considered the best thermometer on the market.

The best thermometers of 2021

When it comes to measuring temperatures, there are many types of thermometer. They range from simple to intermediate to advanced, and they come in handy for various purposes. However, all of them have one thing in common—they are made for different purposes. The kind of thermometer you choose will determine the type of temperatures you are measuring. Here are the best thermometers of 2021 | CNN Underscored.

CNN —  

You don’t have to wait many minutes to read a tiny red line now that mercury thermometers are obsolete. Instead, five distinct kinds of thermometers — rectal, mouth, axillary (armpit), temporal (forehead), and tympanic (remote ear) — may now show a reading on a digital display in seconds. Color-coded backdrops and fever indications, a record of previous readings, and the ability to detect surface temperatures, such as a baby’s bottle, are all useful features.

We talked with two medical professionals to learn more about thermometers. While readings may vary by a degree or two depending on whether you’re using an oral or a forehead thermometer, they all can accurately detect the existence of a fever, they said. So, with the exception of children under the age of three, who should use a rectal thermometer, it’s a matter of personal choice. (You can read the rest of their thoughts below.)

CNN Underscored put 15 of the most highly rated thermometers to the test in our quest for the finest thermometers. To ensure accuracy and consistency, all thermometers were tested on the same individual multiple times. We evaluated the simplicity of use, the speed of the readings, and any additional nice-to-have features in addition to the readings. We discovered three thermometers that should be in every medical cabinet after weeks of testing:

Overall, the best thermometer

Best-thermometers-of-2021-CNN-Underscored

This thermometer can be held up to 2 inches away, and it has a positioning sensor that flashes a light on your forehead to verify you’re measuring your temperature at the correct place on your head. The Braun No-Touch thermometer has everything you need — and more — in a thermometer, including the ability to quiet any noise and an LED display that can be read in the dark.

The best travel thermometer

1630763073_986_Best-thermometers-of-2021-CNN-Underscored

The Elepho eTherm Infrared Ear & Forehead Thermometer, while not as slim as the oral/rectal/axillary thermometers, is the smallest, most durable on-the-go thermometer you’ll find that doesn’t require you to also pack probe covers. You also have two options to take temperature reading: in the ear canal or on the forehead.

Best thermometer for the money

1630763074_307_Best-thermometers-of-2021-CNN-Underscored

The Vicks ComfortFlex Digital Thermometer features three distinct color-coded indications and a big reading display with a backlight. Though readouts took longer than the no-touch alternatives, this thermometer is a good choice for a tiny (and inexpensive) thermometer.

Braun Digital No-Touch Forehead Thermometer

CNN/Jennifer Yellin

Braun Digital Forehead Thermometer with No Touch

By far the finest thermometer we tested was the Braun Digital No-Touch Forehead Thermometer. The instructions are simply written directly on the front of the thermometer, guiding you through the whole temperature-taking procedure. Because each thermometer works a little differently, our medical experts stressed the significance of following the instructions for each one.

When taking your temperature, a light from the thermometer shines on your forehead to verify you’re aiming it at the correct spot (you can read more about thermometer placement below). It will warn you to go forward if you’re too far away by showing “FWD” on the big reading display, a feature unique to this thermometer.

When we tested our own forehead temperature, we were able to get reliable and consistent readings, with temperatures ranging from 98.2 to 98.3 degrees Fahrenheit. While many of the other thermometers we tested gave us similar consistent results (though some did vary by up to 2 degrees between each reading), the positioning light on this one made us feel more confident that we were getting an accurate reading, and we never had to worry about taking temperature readings too far away or in the wrong place on the forehead.

Holding the Braun No-Touch directly on the forehead also works, which may be more convenient if you’re taking your own temperature. Many other no-touch thermometers do not have this feature. The no-touch option will minimize cross-contamination and the danger of transmitting germs if you need to take the temperatures of several individuals.

Thanks to a backlit color-coded screen that shows three distinct colors depending on the temperature measurement — green for a normal reading, yellow for a slightly raised fever, and red for a severe fever — temperatures were simple to read on this thermometer. This fast indication may be helpful if you’re collecting several readings in a row — for example, when children enter their preschool — to determine whether anybody has a temperature immediately. The light-up display may also be used to take a child’s temperature in a dark room when they’re sleeping; a switch on the side can also be used to mute the thermometer so no beeping sound wakes them up.

The thermometer comes with a protective cover to keep the display and probe clean, as well as a three-year guarantee, which is far longer than the majority of the others we examined. A glowing battery indicator will also notify you when the battery life is down to 20%.

One drawback of this thermometer is that it lacks a memory feature for displaying previous readings, which we found to be useful with other thermometers. This is probably not the thermometer for you if you want something that will keep track of your readings, since there are several that do (the iProven No-Touch Thermometer being another favorite of ours).

While this thermometer is more expensive than the others we examined, you’ll receive a thermometer that’s simple to use, has the most straightforward instructions, and provides some of the most accurate and consistent readings — it’s also the best forehead and non-contact thermometer we tested.

Elepho eTherm Infrared Ear & Forehead Thermometer

CNN/Jennifer Yellin

Elepho eTherm Infrared Ear & Forehead Thermometer

Looking to get out of town but want to ensure that a thermometer is packed? If so, the Elepho eTherm Infrared Ear & Forehead Thermometer is the top choice. With lots of functionality and a slim design, this thermometer can easily slide into a toiletry bag or purse.

We found the thermometer to be very simple to slide over the forehead, and it felt better than some of the other forehead thermometers we tested, which were a bit too stiff and harsh. When we tried it on the forehead of a 4-year-old, he agreed that it was smooth and even felt “good.” He also requested that his temperature be taken repeatedly with the Elepho eTherm simply for fun.

This thermometer can also be used in the ear canal, and it’s one of just three we tested that can read both the forehead and the ear canal. (It was also one of the best ear thermometers we tested since it was one of the few that didn’t need probe coverings.) We got much better readings from the Elepho eTherm than the other two. We got consistent and precise findings with the forehead readings, which ranged between 98.4 and 98.6 degrees Fahrenheit – exactly in the typical range for the forehead. It’s also comparable to what we got with our overall #1 choice. Our ear canal temperatures were likewise within normal limits, although somewhat lower: between 98 and 98.24 degrees Fahrenheit.

There’s a big LED display that glows in the dark, and instead of a color-coded backlight, a beep alerts you to a fever. A normal temperature is indicated by one beep, a slightly raised temperature by two beeps, and a fever by four beeps. We preferred the Braun’s color-coded system to sounds — particularly if your kid is asleep — but the beeps were equally effective.

This thermometer has a feature that we particularly like: it automatically turns off after eight seconds. This can help you conserve battery life if you’re using the thermometer on the move. It also passed our toughness test, with no breaking when dropped on our hardware floor.

This thermometer is ideal for throwing in your luggage on your next vacation, thanks to its compact and sturdy construction. You won’t have to worry about probe covers, batteries depleting, or it breaking.

Vicks Comfort Digital Thermometer

CNN/Jennifer Yellin

Thermometer Vicks Comfort Digital

The Vicks ComfortFlex Digital Thermometer is one of the most affordable gadgets on the list, but it still has a lot of useful features, including some that you won’t find in more costly thermometers.

You may take your temperature three different ways with this thermometer: orally, rectally, or under the armpit. We first checked our temperature orally, with and without probe covers (disposable casings that fit over the thermometer tip to keep the instrument hygienic), and both methods yielded comparable readings of 98.3 and 98.8 degrees Fahrenheit. That wasn’t the case with all of the oral thermometers we examined, including the Femometer Infrared Thermometer, which had a 1.64-degree Fahrenheit difference with and without probe covers, making it a far more attractive thermometer.

This good finding indicated that consistent readings could be obtained even if probe coverings were not readily available. If you don’t have access to probe covers, you may clean the thermometer’s tip with soap and water or rubbing alcohol. Fortunately, five single-use probe covers are included in the package to get you started, and ordering additional 200 covers costs approximately $5, keeping it in the budget-conscious category.

We measured our temperature under the armpit and found it to be somewhat lower, at 97.7 degrees Fahrenheit on average. This is to be anticipated when taking a temperature using this technique, despite the fact that it is lower. Taking your temperature beneath your armpit “produces a temperature 1 degree Fahrenheit lower than a temperature obtained orally,” according to the instructions. We also spoke with medical professionals and discovered the explanation behind this: The axillary (armpit) temperature is measured outside of the body (rather than within), thus it is the temperature of your skin rather than your core. To establish whether or not you have a true fever, add about 1 degree Fahrenheit to your temperature taken under the armpit. (Note that we did not test the thermometer’s rectal reading, so we can’t comment on its accuracy in that area.)

The average recording time for measuring temperatures with this thermometer was about 14 seconds. While this is a faster response time than some of the other oral thermometers we examined (which ranged from 10 to 25 seconds), 14 seconds may seem like an eternity to children. Most ear and forehead thermometers, on the other hand, will display the reading in less than a second. Even though the difference is just a few seconds, both a 4- and 7-year-old found the forehead to be preferred to the oral during our testing, so it’s something to think about if you have young children.

Despite the thermometer’s small size, it has a large display with a backlight that shows three different colors based on the temperature — green indicates no fever, yellow indicates 99.9 degrees Fahrenheit or higher, and red indicates fevers of 101.5 degrees Fahrenheit or higher — so you can quickly identify where your temperature falls.

Simply stated, of all the thermometers we examined, this was the best oral thermometer and the best thermometer for infants (where a rectal temperature is advised).

To learn more about thermometers and how they operate, we spoke with two medical experts: Michael Elkort, M.D., a pediatrician at Newton Wellesley, and Jacqueline Jossen, M.D., an assistant professor of pediatrics gastroenterology at Columbia University.

Thermometers come in a variety of shapes and sizes.

Rectal, oral, axillary (armpit), temporal (forehead), and tympanic thermometers were all put to the test (remote ear). While some people prefer one kind over another, we talked to a medical professional to find out which type is ideal for every situation.

Dr. Elkort stressed the necessity of using the correct thermometer for each age group, particularly when taking a child’s temperature. Rectal thermometers are always the best for children under the age of three, according to him, since they record an internal temperature (versus the forehead). Because the ear canals of babies and toddlers are too tiny for an ear thermometer, obtaining an accurate reading orally is difficult (and putting a thermometer in a baby’s mouth is not advised). There’s just less opportunity for mistake with a rectal thermometer. The accuracy of the thermometer reading is critical since clinical judgments are based on it.

He advises utilizing the following — in the sequence mentioned — for accuracy in all children above the age of three: oral, armpit, forehead, and ear. Although Dr. Elkort does not suggest forehead or ear thermometers for children since they may give you a broad range of readings if you do have a fever, they are accurate in detecting a fever and are still highly dependable in monitoring normal body temperatures. Because of this, forehead and ear thermometers are useful for rapidly and readily testing for the presence of a fever when the exact numerical measurement isn’t critical. These thermometers, according to Dr. Elkort, are ideal for measuring the temperature of a big group of individuals since they operate fast and have little risk of cross-contamination. Furthermore, when checking your temperature as a precaution, the most essential thing to know is whether or not you have a fever – the exact temperature reading isn’t as vital.

How do you know if you have a fever?

The average body temperature is 98.6 degrees Fahrenheit. However, since some people have abnormally high or low body temperatures, determining your own typical body temperature is critical. Because many thermometer readings have a small margin, you should establish your usual body temperature with the same thermometer before taking your temperature while you’re sick, so you can compare the reading to a set baseline for normal. You may also follow the American Academy of Pediatrics’ temperature-taking recommendations for children.

If you usually have a 97.8-degree temperature with a particular thermometer, you may be more worried if it gives you a 100.8-degree reading than if it gives you a 99.1-degree reading. The US Centers for Disease Control and Prevention deems a person to have a fever if his or her temperature is 100.4 degrees Fahrenheit or above, according to CNN Health.

This is why your doctor will inquire about the technique you used to take your or your child’s temperature, since they will often add or remove a degree to assess whether the reading is alarming.

Accuracy

Dr. Jossen offered us some pointers on how to get the most accurate readings. First and foremost, be consistent in where you take your measurements. It’s possible that temperature readings obtained from various regions of the body aren’t comparable. Natural differences exist between your right and left ears, for example, and temperatures taken under the armpit (as done with newborns) are less reliable.

Second, make sure that all thermometers are properly positioned. This is particularly essential when using no-touch thermometers to ensure that the instrument is held at the correct distance from clean, clear skin. Dr. Jossen stresses the significance of following the manufacturer’s recommendations while using a thermometer.

Finally, oral thermometers should not be used soon after consuming anything hot or cold, since this may cause readings to be skewed. Allow at least 15 minutes for this.

We chose 15 of the most highly rated thermometers to put to the test after reviewing editorial and user evaluations. To establish consistency, we took several readings for each thermometer (during the same time period) and compared them to the readings of every other thermometer.

We looked at everything you’d want in a thermometer, including usability straight out of the box (and after reading the instructions), display choices, the speed with which you can take your temperature, and any indication that tells you whether you’ve got a fever.

To choose our winners, we used the following criteria to assess each thermometer:

Performance

  • Check for accuracy: We took our temperature with all of the thermometers on the same person over the course of a 10-minute period to see if any of the readings were significantly different from the others.
  • We took our temperature four times (twice each day during the experiment) on the same person with each thermometer to check whether the results were consistent.
  • Speed of reading: We timed every thermometer readings to measure how long it took to get a reading.
  • Is the thermometer simple to use straight out of the box? Do you need to read the instructions? Is it simple to find out all of the additional features?
  • Is the thermometer capable of saving and monitoring past temperature readings?
  • Other features: Does the thermometer include any extra features, such as indications that indicate when a reading is complete, app connection, or the ability to switch from Fahrenheit to Celsius?

Build

  • Temperature reading ease: In both well-lit and poorly lit settings, we recorded how simple it is to read the temperature.
  • Cleaning ease: We took note of how simple it is to clean each thermometer.
  • Is the thermometer set to automatically switch off to save battery life? If that’s the case, we timed how long it takes to turn off.
  • We tested the thermometer’s durability by dropping it twice on a wooden floor. Then, if there were any, we made a note of them.

Warranty

  • Is there a warranty offered by the company?

No-Touch Thermometer by iProven ($29.49; amazon.com)

The iProven No-Touch Thermometer meets the criteria — and more — if you want a thermometer that everyone in your family can use. It was also put to the test by a 4- and 7-year-old with no problems. Anyone — even a kid — can see the temperature recording thanks to the big number display. This thermometer is very identical to our best overall, the Braun Digital No-Touch Forehead Thermometer, except it lacks the location light.

However, if memory is essential to you, the iProven will keep an astounding 50 readings, while the Braun does not. This removes the need to write down readings — and the risk of misplacing that scrap of paper — and ensures that all temperatures are accessible when consulting with a doctor. It will also assist you in determining if your temperature is increasing or decreasing over time.

This is a no-touch thermometer, so it readings from the forehead without requiring any physical contact. This keeps the thermometer clean and prevents germs from migrating from one person to another. This thermometer also measures the temperature of the room, objects, and liquids, whereas the Braun Digital No-Touch Forehead Thermometer does not.

Overall, though, we found the Braun’s forehead guidelines and distance measurement to be more useful in daily usage, cementing its position atop the field.

iHealth No Touch Forehead Thermometer

Amazon

No-Touch Forehead Thermometer by iHealth

No-Touch Forehead Thermometer by iHealth ($24.99; amazon.com)

This no-touch forehead thermometer has a very similar look and feel as one of our favorites, the Elepho eTherm Infrared Ear & Forehead Thermometer, although it doesn’t offer an ear recording option. The thermometer is sleek and slim in design, and much smaller than some of the other no-touch forehead options.

The thermometer is simple to use straight out of the box, and there’s even a one-page handbook with instructions to help you get started.

A built-in infrared temperature sensor gathers more than 100 data points per second in this thermometer. This technique provides for very reliable measurements, and three of the four were identical, while one was just 0.2 degrees Fahrenheit lower.

To use this thermometer, place it an inch from the middle of a person’s forehead and the reading will appear within one second. The thermometer vibrates to signal that the temperature has been recorded. We choose this over a beep since it eliminates irritating noises while still informing you when the temperature recording is complete. There’s a big LED display that shines brightly in the dark. There is no color-coded illumination to indicate a fever, unlike many other thermometers.

If you want a wireless version that can track to your phone, there’s now a $39.99 upgrade that allows you to monitor up to 99 readings on your smartphone using the free iHealth app.

Braun ThermoScan 5 Digital Ear Thermometer ($49.99; amazon.com) Braun ThermoScan 5 Digital Ear Thermometer

If you just need an ear-only reading, the Braun ThermoScan 5 Digital Ear Thermometer is perfect. The prewarmed tip ensures reliable readings, as shown by the fact that two of our readings were a typical 98.6 degrees, while the other two were just 0.1 and 0.2 degrees higher.

The thermometer does need disposable probe filters, and if one is not present, the thermometer will not function. While this helps in keeping the thermometer probe clean and germ-free, it does need having clean filters on hand at all times. If you’re worried about plastic trash, it also produces more of it. A box of filters is provided, so you can use the thermometer straight away, but a 40-pack of replacement filters will set you back $6.

The thermometer snaps into a convenient storage container, and the probe filter box fits neatly inside, so you never have to worry about losing them.

We would have wanted to see a few additional features at this price range, such as the ability to monitor more than just the most recent reading and a backlight to see in the dark. And, unlike the majority of the thermometers we examined, the thermometer does not automatically switch off after a minute of use.

Forehead and Ear Thermometer by iProven ($24.99; walmart.com)

The iProven Forehead and Ear Thermometer, as the name implies, enables you to measure your temperature in two ways: on your forehead or in your ear canal. It was very simple to use this thermometer straight out of the box, thanks to the clearly marked “ear” and “head” buttons.

We took our temperature using both techniques and discovered a difference of approximately a degree between them. Because the instructions say that the ear is more of a “precise measurement” and head mode is a “indicative measurement,” our ear canal readings were more accurate — and constant — which is exactly what we anticipated.

We also found it simple to switch between Celsius and Fahrenheit and see the last 20 measurements. The thermometer also has a color-coded fever indication, which means that if a fever is present, the illumination will become red (99.7 degrees Fahrenheit or above).

One problem with this thermometer straight out of the box is that it does not come with ear probe coverings. While you may use generic covers, which we tested and found to be adequate, going out of your way to get these covers right immediately isn’t always the best option. “If your thermometer needs a probe cover, be careful to use an appropriate cover and change between readings,” advises Dr. Jossen.

Exergen TemporalScanner Thermometer with SmartGlow ($49.99; walmart.com) Exergen TemporalScanner Thermometer with SmartGlow

The Exergen TemporalScanner Thermometer with SmartGlow is the thermometer to choose if you want the longest warranty. With a 5-year guarantee — when most companies only provide a year — you’ll be covered if anything goes wrong with your purchase.

This thermometer is simple to use right out of the box and goes directly over your brow. It’s also one of the few thermometers that provides a five-step instruction directly on the thermometer itself for taking your temperature correctly.

There’s a quiet mode, an eight-scan memory recording option, and the ability to convert between Celsius and Fahrenheit. There’s also a backlight display for reading in the dark, with a gentle yellow glow. If you’re taking a child’s temperature while they’re sleeping, this is advantageous since there won’t be a big color display to wake them up.

On the other hand, the monitor is much smaller than others, there are no color-coded backlights to signal a fever, and the cap proved difficult for children to put on (and keep on).

Wand No-Touch Forehead Thermometer by ThermoWorks ($69; thermoworks.com)

We were fascinated by the ThermoWorks Wand from the start, particularly because it arrived with a tasty bag of jelly beans. We had great expectations since it didn’t seem like any other thermometer we’d seen before, and it was so costly.

We found the ThermoWorks Wand to be simple to use right out of the box. But that was the end of it. The thermometer has a lot of additional features, but we had trouble getting them to function. The thermometer, for example, will record not only body temperatures but also surface temperatures (up to 176 degrees Fahrenheit). Many other no-touch thermometers will accomplish the same thing, but the device’s numerous labeled buttons made it much simpler to figure out. We found it inconvenient because the ThermoWorks Wand just has one button that handles everything.

Despite the little difficulties, the gadget provides precise and reliable readings, can silence all noises, save up to 25 readings, and includes an LED illumination.

Finally, being the most costly thermometer on the list – by a long shot — we don’t think the additional cost is justified.

iProven Thermometer, Oral & Rectal ($14.99; amazon.com)

The iProven is a conventional thermometer that may be used to take your temperature orally and rectally. It’s compact, simple to use, and comes with a few additional functions, but not many.

The tip is very soft, and we didn’t find it irritating beneath the tongue, but the reading took between 19 and 23 seconds each time – the longest of all the thermometers we tried. This lengthy reading isn’t going to cut it if you’re seeking for a fast read or attempting to check a child’s temperature. The thermometer also doesn’t go off until the 10-minute mark, which is almost nine minutes longer than most of the other thermometers on the list — but there is an on/off button that you’ll want to remember to activate so the battery doesn’t go to waste.

Although the iProven thermometer may be used orally or rectally, it comes with a “oral” and “rectal” sticker that can be placed on the thermometer to indicate which body part it is intended for. There are no probe covers included with the thermometer, however we tried probe covers from another thermometer and found that they fit well if you want to use them for hygienic reasons. Even when the probe covers were used, the results were same.

The thermometer is one of the simplest to clean since it is completely waterproof and can be cleaned with only soap and water. It also comes with a plastic storage case to keep the whole thermometer clean when not in use.

Noncontact Infrared Thermometer by Olganda ($39.99; amazon.com)

The Olganda Noncontact Infrared Thermometer operates in the same manner as one of our favorites, the iProven Noncontact Infrared Body, and even has a similar appearance, but the ultimate rating isn’t quite as good.

For begin, despite the fact that batteries are required for the thermometer to function, none were included in the package. With two AAA batteries needed, this isn’t something you’re likely to have on hand. Of course, picking up batteries at your neighborhood convenience shop is convenient, but when you’re ill, the last thing you want to do is run out. Instead, you want to be able to take your temperature right away.

We didn’t get the greatest readings, however, since they were almost a whole degree lower than some of the other noncontact thermometers we tried.

It also failed to hold up in our durability test. The batteries slipped out and the top infrared cover popped off when I (intentionally) dropped the thermometer on the ground. The thermometer, however, worked well after reassembling the parts.

With that stated, the thermometer comes with a handy storage bag — something that most thermometers don’t — and is very simple to use without having to read the whole instruction booklet. It will keep track of your past 20 temperature measurements, adjust the fever warning threshold depending on your body temperature, and provide a one-second reading.

Also, if you need to use a thermometer for other purposes, this thermometer will suffice.

Thermometer for the Forehead and Ears by Choosen ($24.99; amazon.com)

Unfortunately, the Chooseen Digital Forehead and Ear Thermometer did not meet our expectations. Our first concern is getting an accurate temperature measurement, which this thermometer failed to provide. You may take your temperature in two ways with the thermometer: across the forehead and in the ear.

We varied from 96.9 degrees Fahrenheit to 97.2 degrees Fahrenheit among the four readings obtained in our ear canal — which is believed to be more accurate than a forehead reading. So, despite the fact that the results were consistent, we didn’t think it would be the greatest tool for detecting a fever. We next observed similar readings on the forehead, but this time at a temperature of 99.5 degrees. Despite the fact that the instructions indicate that “the measured forehead temperature may vary up to 1 degree Fahrenheit,” we saw a considerable discrepancy between the two, which we didn’t see with our other thermometers with various reading choices.

Despite the thermometer’s accuracy problems, it does offer some useful characteristics, such as the ability to capture non-body readings such as room, object, and liquid temperatures. A dark LED light, a fever warning, and color-coded blacklights are all included. You may also see up to 35 previous temperature measurements, de-mute noises, and switch between Fahrenheit and Celsius with ease.

After you make your order, you may be able to receive this thermometer for free. If you write a review, you’ll get a $30 Amazon gift card or a $30 PayPal refund. Because the product is just $23.99, you could even make a profit.

Infrared Ear Thermometer by Femometer ($19.99; amazon.com)

In a single second, the Femometer Infrared Ear Thermometer will measure your temperature via your ear canal. The thermometer comes with ten protective covers in the package, and although you may use it without them, using them is advised for your sanity.

Within the same time period, we tested our temperature with and without the covers, and our results were alarmingly different. We got temperatures ranging from 98.9 to 99.3 degrees Fahrenheit when we used the protective coverings. When we removed the cover, however, the temperature dropped by more than a degree, to between 97.7 and 98 degrees Fahrenheit. If precision and consistency are important to you, this may not be the ideal thermometer for you.

The thermometer is also very big and comes with a stand to protect it. This is definitely a thermometer to avoid if you’re short on room in your medicine cabinet, particularly because the protective covers don’t fit in the case.

Kinsa Smart Ear Digital Thermometer ($35.99; amazon.com) Kinsa Smart Ear Digital Thermometer

This is the brand to use if you have a chronic illness that requires frequent temperature monitoring. The Kinsa brand, on the other hand, may be more than you bargained for if you’re seeking for something a bit more simple.

Kinsa is unlike any other brand we’ve tried. The thermometer syncs with an app, which records the time and date of each temperature measurement. The gadget will connect with your phone through Bluetooth before taking your temperature, and you will take your temperature in your ear canal like any other ear thermometer. The temperature will appear in the app right away, and you’ll be able to choose which family member got this recording. You may also add any symptoms you or your kid are experiencing, which may be useful when discussing with your doctor.

When you develop a fever, the app will also advise you on what to do, such as when to take medicine and when to visit a doctor. If necessary, you may also set up medication reminders. The software also includes various animations to keep youngsters occupied while their temperature is taken.

While the app is free, you must have your smartphone on you or nearby to monitor your temperature — or at the very least be within Bluetooth range.

Of course, for some, this is a fantastic idea, but the overwhelming majority of people will prefer a thermometer that can be used straight out of the box without the need to download an app.

Kinsa Smart Thermometer (kinsahealth.com; $24.99)

The Kinsa Smart Thermometer has the same app as the Kinsa Smart Ear Digital Thermometer, but you can take your temperature orally, rectally, or under your armpit.

The thermometer comes in a plastic bag that keeps it safe and clean while also being convenient for travel. The tip is bendable, and readings take around eight seconds to capture.

We found the readings to be accurate and reliable, much like the other Kinsa brand thermometer we tried, however you must first install the app before you can take your temperature.
