Electric Hygrometer
Yukio Saitō, Ryunosuke SERIZAWA · Journal of the Society of Materials Science Japan · 1954
Electrical measurement of humidity has hitherto been done by several methods, but we have hardly been satisfied with the results brought about by them for many purposes.A moisture-sensitive element of a hygrometer should have the following characters: it should have no timd-lag in humidity indication, no hysteresis phenomena and also no aging. For those characters, we are going to show a moisture-sensitve element of a hygrometer adopting the electric conduction of a thin film of selenium in humidity environment, and its application on some measurements of humidity.
