To study characteristics of calibration on meteorological temperature sensors, a statistical analysis is made of the calibration data of meteorological temperature sensors from 2010 to 2013 The results show that the overproof rates of both ZQZTW1 temperature and WZP1 temperature sensors are less than 10% and the values are almost the same in four years; among the unqualified sensors, the overproof rates at -30 ℃ and 50 ℃ are significantly higher than those at the other calibration temperature points； at such calibration temperature points as -10 ℃,0 ℃, and 10 ℃, the possibilities that calibration errors of temperature sensors are out of tolerance have the highest consistence and are highly correlated. The results of analysis have certain guiding significance to the selection of the calibration temperature range and temperature points of temperature sensors, as well as warehouse supply.
