Abstract：Temperature standard instruments are studied for the temperature sensor pair of heat meter. Two grade B industrial platinum resistance thermometers (IPRTs) are tested. The experiments showed that the stability of high precise IPRT is 3 mk in the temperature range from 0 ℃ to 90 ℃ per year.The resistance drifts of the IPRTs were eliminated by using W value calculation and the accuracy of the calibration is improved.
