The Most Accurate Thermometer for Children


When your child is feeling under the weather, you don't want to take any chances. Whether you have a sick toddler, elementary school child or teenager, you want accurate, quick results.

Parents rely on accurate thermometers to determine if a fever is present to keep their child home from school, or whether to call a doctor if the temperature exceeds 104°F (40°C). 

What’s the most accurate thermometer to use for children? Temporal artery thermometers are able to measure the body’s core temperature. 

Why Temporal Artery Is The Ideal Method for Children

Temporal artery thermometers are digital thermometers that scan the surface of the forehead.

One advantage to using temporal artery thermometers is that they are non-invasive, which causes less discomfort than other methods. A non-invasive forehead scan thermometer makes it easy to take your infant's temperature without disturbing them from sleeping. The last thing a parent wants is to wake up a tired and cranky child!

Another advantage of the temporal artery method is accuracy. Temporal thermometers scan the forehead area, measuring the temperature of the blood flowing through the temporal artery on the forehead. Standard digital thermometers are inexpensive and used under the tongue, in the armpit, or inserted rectally - however, these are inaccurate methods because they don't measure internal body temperature.

Comparing Temporal vs. Infrared No-Touch Thermometers for Children

When it comes to accuracy, not all forehead thermometers are the same. There is a noticeable difference in the reliability of infrared no-touch and temporal artery thermometers.

While temporal artery thermometers and infrared no-touch thermometers are both non-invasive methods to measure body temperature, they are not the same in terms of accuracy or reliability of a child’s body temperature.

No-touch thermometers are less accurate because they measure the temperature on the skin surface rather than measure core body temperature. The temporal artery method scans the temporal artery that measures the temperature of the blood flowing through the temporal artery, on the forehead.

There are several studies supporting the accuracy and reliability of temporal thermometers.

Taking Your Children Temperature Using a Temporal Thermometer

Follow the steps below to accurately take the temperature of your children: 

  • Place the thermometer sensor in the middle of the child’s forehead.
  • Press and hold the scan button on the thermometer.
  • Slowly move the thermometer across the forehead, scanning toward the temporal artery, the top of the ear. The probe should always be touching your child’s forehead.
  • Stop at the hairline and release the scan button.
  • Remove the thermometer and read the temperature.

A reading of 100.4°F (38°C) or above means your child has a fever. If the reading comes back 104°F (40°C), we recommend calling your primary care provider.
