6 Best Thermometer for Kids and Adults – 2022


6 Best Thermometer for Kids and Adults – 2022

Body temperature control is essential in any home, even more so with the global health alert caused by the COVID-19 pandemic.

The old mercury thermometers were accurate, but they are obsolete due to their toxicity and slowness, so now the most common are digital thermometers.

However, not all models are equally functional and reliable, so conveniently, you inform yourself before buying a thermometer that can give you more than one scare.

Accuracy, response speed, battery consumption, memory, and even quality of materials are fundamental aspects to consider before choosing. In this guide, we have simplified it after analyzing the best models on the market so that your choice is the most reliable possible.

1. Digital Thermometer Femtometer

A cheap and practical digital thermometer takes up little space and is very accurate.

Thermometer Digital Thermometer

  • Weight: 40 grams
  • Measurement time: 20 sec
  • Silent mode: No
  • Memories: No

Infrared thermometers are fast, convenient, and don’t require direct contact, but they’re not always the best choice.

The Thermometer is a digital thermometer, like those of all life, to take the temperature in the armpit, orally or rectally, and has several advantages over an infrared one; it’s small, weighs almost nothing, and is cheaper than “a pistol” type models.

I like this type of Thermometer to carry in my bag or to compare the result that the infrared one gives me if I have any doubts. In addition, being waterproof, it can be washed and disinfected under the tap, and if it falls to the ground, nothing will happen to it (and those of us who have small children know that this happens frequently). I also found it very useful that it notifies you with a beep when the measurement is finished.

The Femtometer is reliable and practical, but do not expect memory, sensors, or ultra-fast reading as in other more advanced models in this comparison. I also miss the lighting on display.

the best

  • easy to use
  • High accuracy
  • Waterproof
  • Low or high-temperature beeps


  • Sometimes the reading time is higher
  • Requires contact with the body
  • It does not come with instructions in Spanish

2. IDOIT Digital Thermometer

IDIOT Digital Thermometer

  • Weight: 140 grams
  • Measurement time: 1 sec
  • Silent mode: YES
  • Memory: 10 dates

The IDOIT is an essential infrared thermometer, ideal if you are looking for a model with good precision but without many additions that increase the price.

This Thermometer is shaped like a gun and is not very big, but the display shows significant digits with high contrast, so it looks great. In addition, when the measurement ends, it indicates the temperature in digits and changes the lighting depending on whether it is normal, high, or very high (green, orange, or red).

It also has an audible alarm (which can be disabled), a 10-measurement memory, and a backlit display for viewing at night. Something efficient if you have babies at home is that it allows you to measure the temperature of the food.

From my point of view, it is accurate and fast (it measures in just 1 second), but the quality of the materials can be improved, so I don’t see it as a good option for frequent use.

the best

  • fast measurement
  • Large, backlit display
  • Fever identification system (3 types of lighting)


  • It does not include a bag or case
  • A little more robustness is missing in the casing
  • It does not have an on/off button

Braun PRT2000 ThermometerA practical, accurate, and suitable thermometer for babies, thanks to its flexible tip

4,024 Reviews

Braun Digital Thermometer flexible tip

  • Weight: 20 grams
  • Measurement time: 8 sec
  • Silent mode: No
  • Memory: 1 date

Among digital contact thermometers (armpit, mouth, rectum), this Braun model stands out for its speed of measurement and its flexible tip, which facilitates handling and increases its resistance to breakage.


Its strikes me that this model allows you to select the measurement mode among the three available (from 0 to 3 months, from 3 to 36 months, and more than 36 months) in this way. Its increases precision even more since it is not the same as taking a newborn baby’s temperature as it is of a 5-year-old child, for example.

It is light, accurate, and affordable. This flexible Thermometer is one of the best thermometers for babies since it is one of the few models that allow you to change the settings to specify the age. However, it can be used ideally for all family members. It is also designed waterproof, and its cleaning and disinfection are straightforward.

the best

  • Accurate, fast, and easy to use
  • Suitable for the whole family and objects
  • Show smiley icons depending on the result
  • Memory


  • A button must be held down during measurement

3. Beurer FT85 Digital Thermometer


A very versatile digital thermometer, with which you can measure the temperature of adults, children, babies, and even food or objects.


Beurer FT85 Digital Thermometer

  • Weight: 90 grams
  • Measurement time: 1 sec
  • Silent mode: Yes
  • Memory: 60 data

This well-known Beurer blood pressure monitor model stands out for its ease of use and versatility since it measures the temperature of adults, children, babies, and even objects (milk, water, infant formula… ).

This Thermometer incorporates a large LCD screen, and I liked the happy or sad faces that it shows on the screen when giving the results since it allows you to see if the temperature is within normal limits with a glance.

I would also highlight the memory, which is 60 data sets, more than enough to follow the temperature evolution of all family members.

The Beurer FT85 is a functional and reliable thermometer, and the price is not bad considering that it is a model of a recognized and veteran brand in the sector. In addition, if you can afford it, you also have the FT100 version that includes a distance sensor, so you can ensure that the measurement is correct at all times.

the best

  • Accurate, fast, and easy to use
  • Suitable for the whole family and objects
  • Show smiley icons depending on the result
  • Memory


  • A button must be held down during measurement

4. Braun IRT 6520 Digital Ear Thermometer

The best Thermometer for babies and children, an exact ear model suitable for use by newborns.

Braun IRT6520 baby and child ear thermometer

  • Weight: 120 grams
  • Measurement time: 1 sec
  • Silent mode: Yes
  • Memory: Yes (9 dates)

When we need to control the temperature in babies, it is advisable to use an ear thermometer such as the Braun IRT 6520 since it is much simpler and faster. And less annoying for the little ones, in addition to the measurement in the ear. It is more precise than on the forehead. It is closer and unhindered to the heat center of the brain.

This Thermometer has a sensor that ensures that the placement at the time of measurement is correct and a probe that is preheated just before measurement to prevent the Thermometer’s tip from cooling the ear and altering the result.

It also allows you to set the age of the child or baby to adjust the accuracy of the result further and displays the data on the backlit screen, both in numbers and in color code, to interpret it at a glance.

the best

  • Measurement in the ear more accurate than in the forehead
  • Correct placement sensor
  • Memory to save measurements
  • Configurable by age
  • preheated probe


  • It does not allow the measurement of objects or food

5. Xiaomi iHealth PT3 Digital Thermometer

An infrared thermometer is very easy to use and with a distance, sensor to avoid erroneous measurements.


Xiaomi iHealth PT3 Digital Thermometer

  • Weight: 90 grams
  • Measurement time: 1 sec
  • Silent mode: Yes
  • Memories: No

Xiaomi is making a niche for itself in the field of health, even surpassing much more established brands, and as it usually does, with prices that are difficult to compete with.

The Xiaomi iHealth PT3 is a minimalist thermometer, do not expect a model with numerous buttons and a wide variety of functions since this Thermometer focuses mainly on offering maximum user precision. And to ensure the accuracy of the measurements, it incorporates a sensor that guarantees the correct measurement distance and another that counteracts variations in ambient temperature.


In addition, it does not emit loud sound alerts that can wake your child by monitoring their temperature while they sleep.

It is simple, precise, and silent (there is only a slight vibration to warn the end of the measurement). However, there is something that I did not like, and that is that the same button that you have to press to measure is also used to change the ºC to ºF, and sometimes you can change the measurement system by mistake.

the best

  • Ambient temperature sensor to correct deviations
  • measuring distance sensor
  • Easy to use and interpret


  • A single button to measure and change from ºC to ºF can lead to confusion

6. Withings forehead thermometer

The best-infrared Thermometer of those analyzed is very reliable and with Bluetooth to see the history on a smartphone.


Digital Thermometer

  • Weight: 75 grams
  • Measurement time: 1 sec
  • Silent mode: Yes
  • Memory: Yes (8 users)

In case you don’t already know, Withings is the brand previously known as Nokia, and it now competes with the best in health devices. The Withings thermometer is nothing like the other models I’ve reviewed, … let’s see why.

This Thermometer has 16 infrared sensors. It is not a standard forehead thermometer since, to use it correctly, you have to measure in the temporal artery (in the temple or lateral of the forehead) since it is more precise than the measurement in the forehead. Front.


It does not need direct contact; by putting it at 1 cm, the measurement is exact, showing the result on a led display in numbers and color code. It also allows you to record the data of up to 8 users and transmit it via Wi-Fi or Bluetooth to a smartphone to keep track of each family member.

It is not a cheap thermometer (for me, that is its main drawback). Still, it is far superior in performance and reliability to the vast majority of thermometers on the market.

the best

  • FDA approved accuracy
  • no contact needed
  • Register up to 8 users
  • Wi-Fi and Bluetooth connection
  • quality materials


  • It does not include a storage case
  • It does not work for objects

Still not sure which digital Thermometer to buy? We help you…

One of the first decisions we make when we feel sick is to measure our temperature since fever is usually one of the first symptoms that our body manifests when faced with an ailment.

Therefore, a thermometer is a tool that we feel is essential in any health center, home, or public establishment.

Until not long ago, we used mercury thermometers, although these are now out of the market due to the toxicity of said liquid metal and have been replaced by other alternatives. And is that new technologies have allowed progress in this matter, allowing the creation of more practical. Fast and precise thermometers, without harmful materials, as with digital thermometers.

Below we will see a series of recommendations that will help you, with the idea that you choose the one that best suits your needs.

reliability and precision

When choosing a digital thermometer, always consider those that will offer you the most outstanding possible reliability and precision when taking temperature measurements.

To determine which Thermometer is more reliable, it is necessary to analyze the precision, and the most recommended is that it has a margin of error between 0.1 and 0.3 ° C.

Also, remember that digital thermometers for clinical use that are also used in homes generally measure temperatures between 34 and 42°C and must be precise. So if the variation or margin of error is higher than two-tenths, it is not a recommended model since the measurements must be correct, especially if you are to measure the temperature at lower temperatures.

Choosing reliable thermometers that offer sufficient autonomy to take temperature measurements for long periods without continually replacing the device’s batteries is also essential.

easy to use

Without a doubt, it is an essential aspect when choosing one model or another.

If you are going to give the Thermometer a merely clinical use; that is, to take the temperature of your family members, the best option is a model without excessive functions that could hinder a more specific help.

In this case, therefore, you have to value the product’s simplicity more than the variety of functions. Of course, distance sensors and sound alerts can significantly facilitate the use of the digital Thermometer.

Almost all current thermometers incorporate this type of sound warning, although ideally you can activate and deactivate the alert depending on your needs.

response time

This factor depends on the demands of each user.

As you have seen, non-contact infrared thermometers are very fast, allowing you to take the temperature in 1 second or a little more.

For their part, digital thermometers placed in the armpit, rectum, or mouth usually take between 10 and 120 seconds to take the measurement.

Naturally, a quick temperature check is something to keep in mind if you have young children who rarely sit still when measuring their body temperature.

Materials and ergonomics

Fortunately, the use of mercury in thermometers is no longer necessary. Today, they are manufactured with materials that do not risk the integrity of people, especially younger children.

In the case of digital body contact thermometers, these are made up of a front panel with a small screen where the digits are displayed and usually have two buttons, the one that starts the measurement and the one that stops and turns off the device.

They are made of plastic or resistant synthetic materials and incorporate a tip (or probe) that is usually metal or flexible rubber.


Most non-contact infrared thermometers are also made with a strong plastic shell that surrounds and protects the sensor (or multiple sensors), the optical system, and the algorithm calculation unit.

They are small in size and usually have a modern and ergonomic design for easy handling. So more than the quality of the devices’ materials, you should look at the design. Robustness and dimensions of the product so that they follow your requirements.

storage memory

Not that it is a prerequisite for a thermometer, but data collection is very convenient for recording the temperature of long-term or chronic patients. This way, you can see the variations you have experienced and inform your doctor precisely.


Generally, the consumption of digital thermometers is deficient. However, we recommend you check their autonomy (especially if you will use them a lot) and check if the batteries necessary for their operation are easy to get at any hardware store.

In addition, you can opt for a model with the option of automatic shutdown. This way, you will avoid excessive battery consumption due to forgetting to turn off the Thermometer.


Some models of digital thermometers not only measure the body temperature of people but can also measure the temperature of the environment and the temperature of liquids and objects.

So, depending on your needs, you can opt for this more versatile and practical Thermometer for different uses

. Such as in the kitchen or the workshop.


If the Thermometer has a large and illuminated LCD screen, you will be sure to display the temperature quickly and easily, even in rooms with low light.

It should be remembered that non-contact infrared thermometers have larger screens and night lighting.
