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 utilitizes
a thin film polymer capacitive type relative humidity sensor as
hygrometer sensor, offering excellent recovery from 100% moisture,
and fast response time and durability.
