湿度传感器的简易现场校准方法

在自动气象站的使用中发现，湿度传感器在极端湿度天气的出现后常出现示值不准，必须校准和订正，基层台站往往不具备这样的及时校准能力，影响气象数据的准确性。本人实践中发现：利用氮气、LiCl过饱和溶液和NaCl过饱和溶液可以现场简易校准温湿度传感器。

A simple field calibration method of humidity sensor.

Found in the use of automatic weather stations, the humidity sensor often shown value are not allowed in the extreme humidity weather, must be calibrated and corrected, base stations often don＇t have the ability to calibrate such, affecting the accuracy of meteorological data. I found the practice： the use of nitrogen, LiCl supersaturated solution and NaCl supersaturated solution can be a simple site calibration of temperature and humidity sensor.
