Thermo-Hygrometer Model CA846

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