气候试验箱湿度测试性能研究

Study on humidity testing performance of climate test box

通过试验对伟思富奇C340气候试验箱的湿度测试进行研究。为了使研究结果能够运用到日常省级自动气象站常规湿度传感器检定业务中,选用广泛应用于自动气象站的HMP155A湿度传感器。根据试验结果得出较为合理的C340气候试验箱的湿度稳定时间、湿度均匀度和波动度,为自动气象站湿度传感器的日常检定工作提供参考。

The humidity test of Weisi Fuqi C340 climate test box was studied through experiments.In order to make the research results apply to routine humidity sensor verification of provincial automatic weather station,HMP155A humidity sensor widely used in automatic weather station was selected.According to the test results,the more reasonable humidity stabilization time,humidity uniformity and fluctuation of C340 climate test box are obtained,which can provide reference for routine verification of humidity sensors in automatic weather stations.
