Abstract:The development and characterization of cesium, sodium heat pipe blackbodies 270~1 000 ℃ at National Institute of Metrology is described. It includes cesium heat pipe blackbody source 270~600 ℃, sodium heat pipe blackbody source 500~1 000 ℃, standard thermometer device and data acquisition system. The cesium, sodium heat pipe performance is tested, including temperature uniformity of the three-zone furnace, temperature stability of the blackbody, axial temperature uniformity of the blackbody cavity, temperature uniformity of the blackbody cavity aperture, temperature uniformity of the heat pipe thermometer well and so on. The combined standard uncertainty is 0.09~0.13 ℃(k=2) in the temperature region from 270~1 000 ℃.
