Capacitive humidity element based humidity & temperature transmitters are ideal solution for detecting relative humidity and temperature in applications such as HVAC in residential & commercial buildings. 

 

Feature:

The capacitance element based transmitter is one of the most stable transmitters available and no recalibration required, transmitters are temperature compensated and calibrated.

 

Application：

HTW3000 transmitters are problem-free and accurate with long-term reliability by apply unique HydroProbe® digital technology, our transmitters are developed for high-precision measurement of relative humidity & temperature and transmitters are available for wall & duct & outdoor mounting.
