Abstract In order to prolong the service life of the fixed point blackbody and simplify the use process, based on the design and use experience of the heat pipe blackbody and the traditional graphite crucible blackbody, an improved package fixed point blackbody was developed. The second-class standard platinum resistance and transfer radiation thermometer are used to carry out the reproduction tests of the tin fixed-point blackbody. After more than 20 cycles of melting and freezing, there is no rupture and metal leakage in the improved encapsulated fixed point blackbody. The average value of multiple tests is 231.909℃, with the help of the standard platinum resistance thermometer, and the expanded uncertainty is 0.015℃(k=2). While with the fixed point blackbody used to calibrate the transfer radiation thermometer, the average value of multiple tests is 231.85℃, and the expanded uncertainty is 0.096℃(k=2).
