Medial Grade Non Contact Forehead Infrared Thermometer With Back Light Display
Human body infrared thermometer
Infrared thermometer consists of optical system, photodetector, signal amplifier, signal processing, display output
and other parts. The optical system gathers the target infrared radiation energy in its field of view, and the size
of the field of view is determined by the optical parts of the thermometer and its position. The infrared energy is
focused on the photodetector and converted into a corresponding electrical signal. The signal passes through the
amplifier and the signal processing circuit, and is converted into the temperature value of the measured target
after being corrected according to the internal therapy algorithm and target emissivity of the instrument.
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.
