DY-HT3000 Ultra-high temperature blackbody radiation source

Black bodies are mainly used in the field of temperature measurement in industry, and the main product is black body furnace. The comparison method is usually used for the calibration and verification of radiation thermometers, that is, through a high-stability radiation source (usually a black body radiation source) and other supporting equipment, the temperature reproduced by the standard device is compared with the temperature reproduced by the tested radiation thermometer to determine whether it is qualified or to give a calibration result.

As a standard radiation source, the standard black body is mainly used to calibrate radiation thermometers, infrared thermometers and radiation temperature sensor detectors. Our company currently has advanced black body technology, a full range of black body products with a wide temperature range. The product is small in size, light in weight, and easy to carry. It is not only suitable for the calibration of radiation thermometers in laboratories of metrology institutions at all levels, but also can be used for on-site calibration.

Product Introduction of Blackbody Temperature Calibrator

Definition of black body: an object that can absorb all external radiation energy and radiate all its own energy at the same time.

The main technical indicators of black body: emissivity of black body, diameter of black body cavity, temperature uniformity and uncertainty of radiation temperature. Therefore, in order to ensure the product quality of black body, black body is usually designed according to temperature segmentation. Usually what we call black body is artificial black body. The emissivity of artificial black body is close to 1, but not equal to 1.

The main function of black body is to generate standard radiation at a certain temperature. Therefore, it is mainly used to calibrate various radiation thermometers in temperature measurement, such as optical pyrometers, infrared thermometers, infrared thermal imagers, etc.
