在自制的饱和盐溶液静态溶液湿度发生器内,对常用的电容式温湿度仪和毛发湿度表进行的湿度测量,并与选取的四种盐的湿度理论值对比。结果表明:HUMLOG10电容式温湿度仪性能稳定,在40—76%RH的区间内,湿度恒偏离理伦值3%RH左右,经湿度补偿后与自制的湿度发生器很好吻合,适用文博单位使用;自制的固定点湿度发生器设备简单,使用方便,湿度值稳定,可用于文博单位对湿度设备校正。
In the homemade saturated salt solution static solution humidity generator, the commonly used capacitive temperature and humidity meter and the hair hygrometer were measured and compared with the theoretical values of the selected four kinds of salt humidity. The results show that: HUMLOG10 capacitive temperature and humidity meter performance is stable, in the range of 40-76% RH, the humidity deviation from the ration of about 3% RH, after humidity compensation with homemade humidity generator is very good fit for the Expo unit Use; home-made fixed-point humidity generator device is simple, easy to use, the humidity value is stable, can be used for cultural unit humidity equipment calibration.
