Principle:

It uses the infrared detection temperature theory,as all substances can produce different length electromagnetic wave when it reaches the absolute zero degree temperature;then transmit energy to the open air and form all kinds of different wave light zone;however the size of spread energy and the wave length of distribution have very direct relationship with the temperature of substance’s surface,so making this product.

Detective theory

It consists of optical system;photoelectric detective equipment;signal amply and dealing tools;display output.which just by these equipments turn the light signal into electric signal,then detective the size of voltage and by itself inner and complicated program calculation to get a temperature size.
