Instruction Manual for Expendable Dew Point Hygrometer.
Abstract
The Expendable Dew Point Hygrometer is a lightweight, battery powered, automatic dew point hygrometer developed for tropospheric balloon soundings. It is designed to be used in conjunction with a radiosonde in gathering meteorological data. The measurement of dew point temperature is accomplished by a thermistor mounted in a dew point sensor which senses temperature as a resistance and provides a signal to the radiosonde. The radiosonde is a balloon-borne, battery powered, meteorological instrument that automatically transmits radio signals relating to the atmosphere pressure, air temperature and dew point temperature of the upper air to ground receiving equipment.
