In nature, all objects whose temperature is higher than absolute zero continuously emit infrared radiation energy to the surrounding space. The size of the infrared radiation energy of an object and its distribution according to wavelength are closely related to its surface temperature. Therefore, the infrared thermometer can accurately measure its surface temperature by measuring the infrared energy radiated by the object itself, which is the objective basis on which infrared radiation temperature measurement is based.
Infrared thermometer Packing information:
Bare metal weight (without battery): 62.5G
Infrared thermometer is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output and so on. The optical system converges 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 their positions. 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 algorithm and target emissivity of the instrument. In addition, the environmental conditions of the target and the thermometer, such as temperature, atmosphere, pollution and interference, etc., should also be considered to affect the performance index and correction methods.
