Part of the book series: Springer Handbooks ((SHB))

Abstract

For measurements of atmospheric humidity, a variety of different techniques has been used in the past, such as hair hygrometers, polymer sensors, optical instruments, and also those based on thermodynamic properties of moist air. Current sensor technology is mostly based on the psychrometric method, dewpoint measurements, and optical measurements, as well as capacitive sensors. Of special interest are the psychrometric theory and the theory of optical measurements. Technical specifications, exposure recommendations, necessary maintenance associated with different methods, as well as methods of quality control and calibration are presented.
