摘　　要：本文根据JJG 499-2021《精密露点仪检定规程》对露点发生装置的标准湿度发生器的要求,研发了基于饱和法及分流法的露点发生装置。同时,在露点(-70~+20)℃发生量值范围内,使用冷镜式露点仪进行量值测量,对发生露点的稳定性进行分析,并进行不确定度评定。结果表明:该装置量值和精密冷镜式露点仪湿度标准在不确定度范围内一致,满足各种常用露点仪的计量校准检定工作。According to the requirement of standard humidity generator of dew point generator in JJG 499-2021"Verification Regulation of Precision Dew Point Instrument",the dew point generator based on saturation method and split method is developed in this paper.At the same time,in the range of dew-point(-70~+20)℃,the cold mirror dew-point meter was used to measure the dew-point stability,and the uncertainty was evaluated.The results show that the measurement value of the device is consistent with the humidity standard of precision cold mir-ror dew point instrument in the uncertainty range,and can meet the calibration and verification work of various common dew point instruments.
