Abstract:In response to the low accuracy and reliability of temperature measurement standard for meteorological purposes, the accuracy and reliability of quantity value transmission are low. A verification scheme for the calibration result of the second-grade platinum resistance measurement standard device has been designed. This scheme takes the calibration result of a provincial second-grade platinum resistance measurement standard device as an example and verifies it through transfer comparison method and peer comparison method. The results show that the absolute deviation values of the corresponding calibration results between the device and the high-level measurement standard device are both less than 0.019 ℃, meeting the requirement of the transfer comparison method. The absolute deviation of the weighted arithmetic mean of the corresponding calibration results between this device and the four measurement standard devices participating in the comparison is less than 0.007 ℃, which also meets the requirements of the peer comparison method. Therefore, both methods have been validated. The results indicate that the second-grade platinum resistance measurement standard device can obtain accurate quantity transfer data, This scheme can ensure the accuracy and reliability of meteorological temperature measurement standard and quantity value transmission.
