便携式高温露点湿度发生器的研制

Development of a Portable High Temperature Dew Point Humidity Generator

为了解决高温露点的溯源问题,研制了一种便携式高温露点湿度发生器,能够现场开展室温至95℃的各种工业露点仪的校准,配合测试腔和高温恒温环境可以开展高温温湿度计的校准,经比对表明:该发生器在露点温度95℃时,其最大允差优于1.0℃。该发生器体积小、重量轻,非常适合现场开展校准工作。

In order to solve the problem of high dew point traceability,this paper developed a portable high-temperature dew point humidity generator.It can not only calibrate various industrial dew-point meters at room temperature to 95℃,but also calibrate high temperature and humidity meters with the test chamber and constant temperature environment.The maximum permissible error of the generator is better than 1℃through contracting with a 373 high temperature dew-point meter at the dew point temperature 95℃.Because of its small size and light weight,this generator is very suitable for field calibration.
