1 前言 各种各样的湿度传感器已得到普及,但真正可靠的仪器出乎意料地少。这主要是由于传感器本身随时间而发生质量变化使性能降低所致。人们熟知,性能不降低的仪器是镜面冷却式露点仪。 不能简单地获得湿度的标准也是因为测量湿度很难。湿度的标准如果象质量砝码那样有一个装入容器能简单移动的恒湿容器就
1 Introduction A wide range of humidity sensors have gained popularity, but truly reliable instruments are surprisingly few. This is mainly due to the quality of the sensor itself changes over time to reduce performance. It is well known that the instrument whose performance is not degraded is a mirror-cooled dew point meter. The standard that humidity can not be easily obtained is also due to the difficulty of measuring humidity. Humidity standards If the quality of the weight as a container can be easily moved into a container of moisture
