The acceptance work was conducted by researcher Lu Xiaofeng and researcher Wang Jinghui. The acceptance of the BB-PyroG3000 ultra-high temperature blackbody radiation source has laid a solid foundation for the smooth development of future inspections. It has made a qualitative leap in the radiation temperature measurement level of the Metrology Institute of Jiangsu Province, further highlighting the radiation detection capability of the Metrology Institute of Jiangsu Province, and providing effective support and escort for the rapid economic development of Jiangsu Province and its surrounding areas.

It is reported that since the issuance and implementation of the new procedure JJG 856-2015 “Working Radiation Thermometer Verification Regulations”, in order to better meet the requirements of the regulations and the detection requirements of various industries for radiation temperature measurement and high-temperature segment, Jiangsu Province in 2017 The temperature chamber of the Institute of Thermal Engineering purchased the BB-PyroG3000 ultra-high temperature blackbody radiation source developed by Russia's National Institute of Metrology. The effective emission rate of the device is better than 0.9995, and its technical level is internationally leading. It has been successfully applied to NIST, PTB, NPL, NIM, etc. National measurement laboratory.
