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.
