摘要探讨了提高环境试验设备温度校准能力的几种方法,即使用更高级别的标准器对温度巡检仪传递温度和对测温铂电阻加修正值使用。使用该量传方式后,通过校准温湿度仪表检定箱,并计算温度校准结果的不确定度,发现其明显优于之前的评定结果,扩展不确定度为0.26 ℃（k=2）。该方法的优点在于挖掘了现有的测量设备的潜力,充分利用实验室既有的测量设备,为提高环境实验设备的校准能力提供了新思路。

Abstract：Discussion on improving environmental test equipment temperature calibration capabilities in several ways, both a higher level of standard device for temperature data logging devices is used to transmit temperature and platinum resistive temperature correction value is used. After using the amount of transfer mode, temperature and humidity meter through the calibration test case, and calculates the temperature calibration uncertainty of results found assess the results of its much better than before, expanded uncertainty is 0.26 ℃ (k = 2). The advantage of this method is full use of existing laboratory measurement equipment, and provides a new idea to improve the environmental test equipment calibration capability .

Key words： metrology environmental testing equipment calibration uncertainty
