Whether you're getting your family ready for the flu season or just need to have a reliable thermometer on hand, being able to take your family's temperature at home is essential. When it comes to the proper way to take an accurate reading for children, the American Academy of Pediatrics notes that rectal temperature readings are the most accurate and is the method that should be used for babies 3 months old and younger.

Depending on the needs of your family, you may want to opt for a thermometer that has additional features like the ability to store previous temperatures or an accompanying app. Choosing a thermometer that is easy to use and provides accurate readings is also essential.

We've rounded up the best thermometers for your family that you'll want to keep on hand.

Unlike the ear thermometers you probably remember growing up, this thermometer doesn’t require disposable plastic covers that can interfere with fever reading, instead, the BPA and Latex-free reader can be easily cleaned with a soft cloth or cotton swab and just a dab of 75 percent alcohol.   

In addition, this thermometer connects to a smartphone app via Bluetooth that not only tracks your family’s fever history but offers personalized suggestions on when to see a doctor. It also reminds you when it’s time to take your medications again. And with a battery life that lasts for two years or up to 1,000 readings, you won’t be panicked to search for new batteries when someone you love is already feeling their worst.

This durable thermometer is also waterproof, making it super easy to clean with just a little water and soap. Like the other options on this list, this thermometer is a great mercury-free option.

Being that this can be used rectally, this is a great option for newborns since a rectal temperature is the most accurate. If your household doesn't get sick much it is also an affordable option to keep at home in case a fever strikes.

Exergen Temporal Artery Thermometer TAT-2000C

  • 8 temperature memory

  • Can silence beeper 

  • Must use specific spot on forehead

If your child is consistently picking up bugs and viruses on the playground, make sure you have a reliable and easy-to-use thermometer on hand. Say goodbye to the discomfort of under-the-tongue, inner ear, or rectal thermometers. Instead, this option takes the temperature by capturing the heat from the temporal artery through the forehead skin.

Other great features include a lightly glowing display to help you see when you’re taking temperatures in the dark, an automatic shut-off feature to help you preserve the batteries for when you really need them, and super-simple one-handed functionality. This thermometer is completely mercury-free, so you know it’s safe for even the youngest members of your family.

The AAP reminds parents that for the most accurate reading under the age of 3 you should take a child's temperature rectally. You can use this for a quick check and then try rectal for a more reliable number. Babies under 3 months old always need to have their temperature taken rectally.

Best No-Touch: Braun No Touch Digital Thermometer NTF3000US

Braun No Touch Thermometers

If you find yourself needing to take temperatures from finicky kids when they’re sleeping, invest in this no-touch option from Braun to make it super simple. This Braun thermometer also has a silent option so you won’t disturb your little one’s sleep when they’re already not feeling well.

To take your loved one’s temperature, simply hold the thermometer up to 2 inches away from their forehead, and the non-invasive technology will do the work for you. When you use this thermometer, the backlight will change from green to yellow or red, each indicating the severity of the temperature.

It’s a little pricier than most of the other options on this list, but the discreet technology is worth the splurge. You'll know that you’re in safe hands with this doctor-preferred brand: According to the July 2017 Ardent Consulting Survey, more pediatricians use Braun than any other thermometer brand.

Best Ear Thermometer: Braun ThermoScan 5 IRT6501 Digital Ear Thermometer

Braun ThermoScan 5 IRT6501 Digital Ear Thermometer
  • Pre-warmed tip

  • Large screen is easy to read

  • Sanitary disposable filters

  • Screen isn’t backlit

  • Must be used with filter

This easy-to-use thermometer is suitable for the whole family—babies, kids, and adults alike. Buyers praise this thermometer’s accuracy and ease of use. This ear thermometer uses disposable lens filters to make it easy to switch between users without having to clean, and also because Braun knows that a buildup of earwax can impact the accuracy of the reading.

Thanks to Braun’s pre-warmed thermometer tip, temperatures are more accurate than other brands whose cool tip can lower readings. Braun stands by ear temperature readings as the most accurate way to detect fever. The brand explains that the blood supply in the eardrum shares the temperature control center of the brain, so it’s the best place to detect unusual temperature changes.

Location: Ear | Reading Time: 2-5 seconds | Battery: AA

Final Verdict

For a larger family, the Braun No Touch Digital Thermometer (view on Walmart) offers quick, no-touch readings that are reliable and accurate every time. If you are caring for infants under 6 months old, having the iProven Oral and Rectal Thermometer (view on Walmart) on hand for rectal readings is essential.

What to Look for in a Thermometer


Beyond simple temperature readings, some thermometers will store a history of your family’s temperatures, and some will even provide advice on when you should see a doctor. There are also thermometers that do double duty and can be used to check the temperature of things like baby formula. How many bells and whistles you want will depend on how often you use a thermometer, the size of your family, and your general preferences.

Ease of use

From cleaning the thermometer to getting a temperature reading no matter the circumstances (think squirmy and/or sleeping children), there are some thermometers that make the job a lot easier than others. Also, consider the battery life of a thermometer. There are few things more frustrating than someone spiking a fever in the middle of the night only to find that the thermometer is out of batteries.


The most important quality you want in a thermometer, of course, is accuracy. You want to be able to rely on the results to help you make the best health decisions for you and your family. While rectal readings are recommended for children under 3, for older children and adults, there are a variety of methods thermometers use to produce accurate results, including some models that don’t even have to touch the skin.
