Abstract :
An electric hygrometer is a device used to measure relative humidity (RH) by electrical means. Mechanical methods are exemplified by the hair hygrometer and the sling Psychrometer. An electric hygrometer was developed by Dunmore1 and used extensively in radiosondes to obtain upper-air data for the United States Meteorological Service. The electric hygrometer described in this report has a lower resistance than the Dunmore hygrometer. The lower resistance of this hygrometer allows direct operation of relays with the hygrometer current.
