Product Description


Product description:

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


 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.

All transmitters can be equipped with industrial-class LCD display, LCD shows both humidity and temperature.
