We all know that the most traditional temperature measurement is to use thermocouples, which is a contact temperature measurement method. In very high temperature or relatively harsh environments, this is not feasible, and infrared thermometers use non-contact measurement. , it does not need to touch the interior or surface of the measured temperature field, so it will not interfere with the state of the measured temperature field, and the thermometer itself is not damaged by the temperature field. The infrared thermometer has a wide measurement range, fast measurement speed, high accuracy and high sensitivity.

Imported infrared thermometers can reach up to several thousand degrees, and the accuracy of repeated readings is this point. At present, most domestic infrared thermometers are incomparable with imported infrared thermometers. The response wavelength is generally different from imported infrared thermometers. Different response wavelengths are used in different segments, and the response wavelengths of domestic infrared thermometers are basically: 8um to 14um.
