Infrared radiation is one of the most widespread electromagnetic wave radiation in nature, and objects have irregular movement of their own molecules and atoms, and constantly radiate infrared energy. The higher the temperature of the object, the stronger the irregular movement of its own molecules and atoms, the greater the energy of radiation, and vice versa, the smaller the energy of radiation. The magnitude of the infrared radiation energy of an object and its distribution by wavelength are closely related to its surface temperature. Therefore, the surface temperature of the object can be accurately determined by measuring the energy radiated by the object itself, which is the basic principle of infrared thermometers. At present, the infrared thermometers we are producing support the temperature measurement range lowest to -50°C~380°C, highest up to 2200°C.
