HTX HVAC Series Humidity-Temperature Transmitter

Brand: Intempco Controls, Inc.

The INTEMPCO HTX series humidity transmitters offer high accuracy, low cost humidity, and temperature measurement that can withstand tough industrial and HVAC applications.

The rugged solid state sensor has high chemical contamination resistance and handles extreme ventilation conditions, like swimming pool environments, with ease. Even water immersion of the sensor will not damage it.
