摘　　要：介绍了一种便携式渗透法湿度发生器的工作原理及研制过程。详细阐述了该湿度发生器的恒温体设计、渗透管选择、气路的优化设计等。该便携式温度发生器可产生-30,-40,-50,-60℃四路定点样气,其发生的低露点标准气体最大误差值在±0.4℃内且总重量仅有10kg左右。试验证明该装置性能稳定可靠,适合开展工业露点仪的现场校准工作。This paper introduces the working principle and development process of a portable humidity generator penetration. It elaborates the thermostat body design of the humidity generator,selection of the permeation tube selection,and design of the gas path optimization. This portable humidity generator can produce sample gas in four routes：-30,-40,-50,-60℃. The low-dew-point standard gas has the maximum error within ± 0. 4℃ with a total weight of only 10 kg. Through the experiment it proves that the device is stable in performance and accurate and reliable in working.
