Radiation Temperature Measurement Method
Sep 21, 2018

All kinds of radiometric methods can only measure the corresponding photometric temperature, radiative temperature or colorimetric temperature. Only the temperature of the black body, which absorbs all the radiation and does not reflect light, is the real temperature. If you want to measure the real temperature of the object, you must correct the surface emissivity of the material. The surface emissivity of materials depends not only on temperature and wavelength, but also on surface state, coating and microstructure, so it is difficult to measure accurately.
