The medium temperature blackbody radiation source is mainly used to calibrate radiation thermometers in the temperature range of (300-1100) ℃. It uses resistance wire heating and can be used in an oxidizing atmosphere. One end is open. In order to improve the effective emissivity, the isothermal blackbody cavity method is used, which involves winding furnace wires unevenly or uniformly winding both ends with auxiliary winding heating to produce a uniform temperate zone. The cavity is isothermal and forms an isothermal blackbody.

Including the metrology certificate of the National Defense Science and Technology Industry First Metrology Testing and Research Center, the technical indicators meet the requirements of current regulations/specifications.
