The Thermo-Hygrometer Model CA846 is a portable, compact digital meter designed for simplicity and one-hand operation. The meter uses an RTD Pt385/1000W as the temperature sensor, providing excellent response time to changes in temperature, good repeatability and accurate readings. The Thermo-Hygrometer also utilitizes a thin polymer capacitive type relative humidity sensor as hygrometer sensor, offering excellent recovery from 100% moisture, and fast response time and durability.
