Relative humidity measurement system

The temperature and humidity detection box of the cold mirror dew point meter was developed by Zhuhai Aobert Co., Ltd., and Oberthur used the British imported high-precision mirror dew point meter to participate in the control of the temperature and humidity test box. The temperature and humidity uniformity and the degree of fluctuation have increased by one level, reaching or even exceeding the technical indicators of the national standard JJG205-2005 temperature and humidity verification box. The perfect combination of mirror dew point meter and temperature and humidity box is realized.
