温湿度变化试验箱湿度场有效性的验证

Validity checking of humidity field in the temperature-humidity changing chamber

湿热试验是考核元器件、材料、传感器、变送器及各类仪器仪表产品性能、质量的重要手段。通过测试温湿度变化试验箱内的湿度,得到湿度场的波动度。提出表征湿度场精度的方法,比较不同测湿的方法,提出改进和提高湿热试验水平的有效方法。

The humidity-heat test is the main method to examine the performance and quality of products such as the device, material, sensor, transducer and various instruments or meters and etc.The humidity field fluctuation is obtained through the humidity test in the temperature-humidity changing chamber, the method for accuracy of the humidity field is proposed,different humidity testing methods are compared, efficient way is put forward to improve the humidity-heat test level.
