摘　　要：针对型号相同和数量庞大的阻容法露点湿度计,通过采用露点传感器校准专用测试筒提高单位时间的校准时效。将露点湿度计在专用测试筒中校准得到的示值误差与在湿度发生器的测试腔中校准得到的示值误差进行比较和验证,由两种测量方法得到结果差异对测量结果的不确定度的贡献可以接受的前提下,采用露点传感器校准专用测试筒来提高工作效率是一个不错的方案。For the same type and large number of Resistance and capacitance dew point hygrometers,the calibration time per unit time is improved by using the special test cylinder for dew point sensor calibration.The indication error of the dew point hygrometer in the special test cylinder is compared and verified with that in the test chamber of the humidity generator.On the premise that the difference of the results obtained by the two measurement methods can contribute to the uncertainty of the measurement results,it is a good scheme to use the dew point sensor to calibrate the special test cylinder to improve the work efficiency.
