Author : Diabetic Corner | Published On : 17 Jul 2026
When checking someone’s fever, using a temporal artery thermometer can give faster and more reliable temperature readings. However, you should understand how it works and its accuracy before buying. Also, don’t hesitate to consult a qualified healthcare professional for better advice.
What Is a Temporal Artery Thermometer?
A temporal artery thermometer is an electronic medical device. It allows you to measure the heat your body gives off in your temporal artery (a blood vessel). This specific artery is ideal for fever detection and runs across the middle of your forehead. These devices are widely used in hospitals, households, schools, and public spaces.
How Does A Temporal Artery Thermometer Work?
This device uses infrared technology to measure your temperature. It acts as a passive receiver that captures the thermal energy naturally radiating from your forehead skin.
The scanning process involves:
Capturing the Heat: The sensor captures hundreds of infrared heat readings per second.
Measuring Blood Flow: The device measures the temperature over the temporal artery.
Calculating Core Temperature: This converts the skin surface temperature into a reliable estimate of your internal arterial core temperature.
How Accurate Is A Temporal Artery Thermometer?
A temporal artery thermometer is highly accurate and clinically validated for tracking temperature trends. This device takes advantage of the temporal artery’s location, as it is an easily accessible artery with constant blood flow. However, it depends on environment and the technique. It serves as an outstanding, comfortable first line of defense for all age groups.

How to Use a Temporal Artery Thermometer Correctly
For more accuracy, you should apply a proper scanning technique. Avoid rushing the device to the skin without checking the conditions.
Ensure the patient has been in a temperature-controlled room.
Make sure the forehead is free of sweat, makeup, hair, or oils.
Position the device properly according to the instructions.
Press the button and scan across the forehead midline toward the hairline.
Release the button, read the digital display, and wipe the sensor tip.
