Abstract

This paper describes in detail the design and construction of an infrared hygrometer to measure absolute humidity in the atmosphere. The hygrometer has good dynamic response compared to other methods and the speed of response is essentially limited by the electronic filters. The hygrometer can be readily modified to measure the humidity for atmospheric research also Use of two infra-red filters for differential measurement which chop the measuring light beam, eliminates completely the errors due to aging of infrared source, atmospheric light scattering and other extraneous disturbances. The calibration procedure is also outlined.
