Temperature measurement principle

The principle of infrared thermometer's temperature measurement is to convert the radiant energy possessed by

infrared rays emitted by the measured object into electrical signals. The amount of infrared radiation energy is

related to the temperature of the object itself, and the temperature of the object can be determined according to

the size of the converted electrical signal. All objects above absolute zero will radiate infrared rays by

themselves. The function of the infrared thermometer is to collect the infrared rays emitted by the object. It will

not emit any harmful radiation at all, so it is completely harmless to the human body. Some people have

misunderstood that infrared thermometers emit radiation to the human body to produce readings. This concept is

wrong.
