双金属冰箱温度计校准方法及不确定度研究

The Calibration Method and the Uncertainty Evaluation of Bimetal Refrigerator Thermometer

根据笔者多年从事温度仪表、温湿度仪表的校准经验,探讨了双金属冰箱温度计的校准方法,并对校准结果的测量不确定度评定进行了详细分析,为从事双金属冰箱温度计计量校准的同行提供参考。

As a temperature monitoring instrument,bimetal refrigerator thermometer is widely applied in the area of medicine and food service industry.However,most of the bimetal refrigerator thermometer can not be immersed in the thermostat bath while calibrating,so the Verification Regulation of Bimetal Thermometer is not applicable.So far,there is no calibration and verification standard of the bimetal refrigerator thermometer.The calibration method of bimetal refrigerator thermometer is discussed in the paper.The measurement uncertainty evaluation of the calibration result is analyzed in detail.
