Abstract:

Measurement of humidity in the full temperature and working condition is a difficult problem in the field of atmospheric observation all the world. Dew-point hygrometer can measure humidity in the full temperature field; however, it has not been put into operation application at present. In this paper, based on the analysis of the development of chilled-mirror dew-point hygrometer in China and abroad, the key technique problems in operation application are discussed in detail.

Key words: chilled-mirror dew-point hygrometer, temperature of dew point, thermoelectric cooling, photoelectric method
