How do you calibrate an infrared thermometer gun?
How to Calibrate an Infrared Temperature Gun
- Switch on the blackbody calibration cavity and give it time to reach an equilibrium temperature. This can take about 30 minutes.
- Adjust the emissivity setting on the infrared temperature gun.
- Place the reference thermocouple on the surface of the blackbody calibration cavity.
Do infrared thermometers need to be calibrated?
An infrared thermometer must be validated against a laboratory calibrated ‘master’ thermometer on a known temperature source. The best way to control the emissivity and temperature of a surface, ensuring that you get the true reading of an infrared thermometer, is by using a solid black body.

Why infrared thermometer is not accurate?
To make things worse, infrared thermometers have an accuracy of ±3 degrees. That means your recorded temperature could potentially indicate hypothermia or fever, even if your body temperature is actually normal. Welp. Plus, they only measure the external temperature of a person, not their internal readings.
Do infrared thermometers expire?
Thermometers do not expire, but they do have to eventually be replaced.
Why is infrared thermometer reading low?
Please note that the “Lo” indicator on the infrared thermometer does not indicate a low battery warning. It indicates a low temperature reading. If you refer to the Troubleshooting section of the User Instructions, in Body Mode, the LCD shows “Lo” when the measuring distance from the forehead is greater than 2 inches.
What is normal reading on infrared thermometer?
While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that “normal” body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
