Products > > Humidity & temperature transmitter and sensor>Room humidity & temperature transmitter SE-MW series

Room humidity & temperature transmitter, output 0~5V DC or 0~10V DC or 4~20mA or RS485 signal

Humidity and temperature sensor/transmitter for Wall Mounting SE-MW series

Full range temperature compensated! The best quality and good price!

 

Selectech 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

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