Main technical indicators of blackbody: black body emissivity, black body cavity diameter, temperature uniformity and radiation temperature uncertainty.So in order to ensure the quality of black body products, usually black body is designed according to the temperature segment.Usually what we call boldface is artificial boldface.The emissivity of the artificial blackbody is close to, but not equal to, 1.The main function of the black body is to produce standard radiation at a given temperature.Therefore in the temperature measurement is mainly used to verify a variety of radiation thermometers, such as optical pyrometer, infrared thermometer, infrared thermograph and so on.Black body in the industry is mainly used in the field of temperature measurement, the main product is black body furnace.
In the calibration and verification of radiation thermometers, the comparative method is usually adopted, that is, through the radiation source of high stability (usually black body radiation source) and other supporting equipment, the temperature reproduced by the standard apparatus and the temperature reproduced by the radiation thermometer are compared, in order to judge whether it is qualified or to give the calibration results.As a standard radiation source, the standard black body is mainly used to calibrate radiation thermometers, infrared thermometers and radiation temperature sensing detectors.At present, our company has advanced black body technology, full product range and wide temperature range of black body series products.
