Wall Mount Humidity and Temperature transmitter, 4-20 mA, dual outputs.Full 0 to 100 %RH measurement
Optimal energy management

The duct and wall-mounted HMD/W 60 transmitters are designed for monitoring relative humidity and temperature in building energy management systems. The combination of high accuracy, stability and reliable operation makes these products the ideal choice for demanding energy management applications.

The duct mount transmitters can also be used in many industrial humidity monitoring applications, where their stability and resistance to chemicals and dust are of great value. A novel feature of these duct mount transmitters is the ability to remove the electronics without disassembling the unit from the duct.

Fast on-site calibration

The accuracy of the transmitters is simple to check using the humidity calibrator. The calibration can be done in seconds with a single potentiometer without disturbing operation. This saves hours of maintenance time and ensures high system accuracy. The calibrator comes complete with carrying case, calibration cables, and NIST traceable certificate.
