We set out to find the most accurate, consistent, fast, and easy-to-read forehead (temporal artery) thermometers – of 2022.

Below you’ll find our top picks and our detailed forehead thermometer reviews.

  Infrared Forehead Thermometer Accuracy

Temporal artery thermometers, known as forehead thermometers, use an infrared scanner to measure the temperature of the temporal artery in the forehead.

The latest research suggests that forehead infrared thermometers are the most accurate alternative to rectal digital thermometers for taking a child’s temperature. However, the environment around you may influence your skin temperature. The tested child/adult needs to be in the same room for 30 minutes if you want an accurate read.

Infrared thermometers can read a person’s temperature very quickly, are easy to use, safe, and easily tolerated by children and babies.

With some thermometers, you don’t even have to touch the skin to read the temperature, which makes them best for testing sleeping children – without waking them up and disturbing them.

They are the best fit for infants older than 3 months and older children, and according to the Mayo clinic, new research suggests that they may also be used for newborns.

Do you add a degree with a forehead thermometer?

User manuals report an accuracy of about 0.4 Fahrenheit degrees, which is not ideal, but all the accuracy in the world won’t help if you can’t use it on a temperamental child. A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What is Considered a Fever When Using a Forehead Thermometer?

According to the Seattle children’s hospital, a forehead temperature of 100.4° F (38.0° C) or higher is considered a fever in both children and adults.

Checking for fever can be done in different parts of your body, including the armpit, mouth, ears, rectum, and forehead.

• An ear temp. is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
• An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
• A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Are Infrared Forehead Thermometers Safe?

Infrared forehead thermometers do not emit any kind of electromagnetic radiation, they only measure infrared heat to determine your temperature. The red beam coming out of the thermometer is visible and harmless and is made to guide the person taking your temperature to the right spot – for an accurate read.

Infrared Forehead Thermometers FAQ

What is a Normal Temperature on the Forehead?

The average normal oral temperature is 98.6°F (37°C), while the forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

How Do You Use a Forehead Thermometer?

If you have a no-touch forehead thermometer, you simply position the device in the center area between the eyebrows, at a 2.5 cm distance.

The thermometer will indicate when the reading is done. With a contact forehead thermometer, you’ll need to slowly slide the thermometer across the forehead toward the top of the ear, until the device indicates the reading is done.

What’s Better – Ear or Forehead Thermometer?

Each of these infrared thermometers has its pros and cons. The ear thermometer can give you more accurate readings with older children who do not mind feeling the probe in their ears.

For younger children, the forehead thermometer is ideal as it is gentle and non-intrusive.
