Is the infrared thermometer accurate and is it radioactive to human body?

Human body temperature is divided into internal ambient temperature and body surface temperature. Body temperature is the temperature of the body, closer to the body temperature is the temperature of the mouth, rectum or armpit.

braun forehead thermometer refers to the temperature of the skin on the surface of human cells, such as the forehead and wrist surface temperature.

Two major types of thermometers

Contact thermometers: Commonly used glass thermometers and medical electronic thermometers, usually placed in the armpit, mouth or rectum.

The accuracy of this thermometer is relatively high, generally at 0.1 ℃ -0.2 ℃.

Non-contact thermometer: infrared forehead thermometer, infrared sieve, infrared ear thermometer, etc..

The accuracy of this thermometer is slightly lower, usually 0.3 ℃ -0.4 ℃.

Combining the advantages of the two thermometers, it is generally recommended to use the infrared thermometer for initial screening, the use of glass thermometer for accurate measurement.

Infrared thermometer method of use

Infrared thermometer generally requires the use of different temperatures is 16 ℃ -35 ℃, it is recommended to choose as much as possible to use in a windless indoor environment.

It is recommended that the infrared thermometer be temperature protected, such as placed in cotton padded clothing

In an indoor environment without wind, it is recommended to measure the position of the center of the forehead, the distance is generally 1-3 cm. In the case of low temperature room and wind, you can test the wrist, neck and other warmer parts of the replacement.
