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 .
