干湿球测湿法和电子式湿度传感器测湿法在现行的湿度丈量计划中运用最为广泛，下面就两者之间的区别加上介绍，便利客户选用：

　　干湿球测湿法的保护相对比较简单，在运用过程中，只需定时的给湿球加水及在恒温恒湿试验箱中定时替换湿球纱布即可，一般不会产生老化和精度下降等问题，更适合于在高温或恶劣环境的场合中运用。

　　而电子式的湿度传感器在近20几年间有了迅猛的开展，湿度传感器于出厂前需做标定，一般状况下一次标定的运用时间为1-2年，如对精度要求比较高的状况下需从头标定，湿度传感器的精度可达2%-5%，运用便利，在实际运用中，需注意尘土、油圬及有害气体等物质污染传感器的功能，所以电子式的湿度传感器更适合在相对洁净的环境中运用。

　　The dry wet bulb method and the electronic humidity sensor method are widely used in the current humidity measurement plan.

　　The protection of psychrometric method is relatively simple, in the application process, only the timing of water wet bulb and in constant temperature and humidity test box in time replace wet bulb gauze can be, generally do not produce aging and decreased accuracy and other issues, it is more suitable in high temperature or harsh environment in the field.

　　The electronic humidity sensor in the past 20 years has been rapid development, from the factory to do humidity sensor calibration, the general situation of a calibration using time is 1-2 years, such as the high precision under the condition of need from the calibration accuracy of humidity sensor is 2%-5%, the use of convenience, in in actual use, the need to pay attention to dust, oil dirt and harmful gas pollution substances such as the function of the sensor, so the electronic type humidity sensor is more suitable for use in relatively clean environment.
