We supply room and duct humidity and temperature sensors as well as outdoor humidity and temperature sensors which are compatible with all common HVAC DDC and Analogue Control Systems.

Our range includes pipe condensation sensors and surface leakage switches.

Most models feature 4 humidity measuring variables with relative humidity and absolute humidity, dew point and enthalpy.


The units are available in wall mount, flush mount and ceiling mount versions as well as duct and pipe immersion sensors.

The sensor outputs are active 0...10V or 4...20mA, selectable via DIP switch.

Passive temperature outputs such as PT100, PT1000, NTC10k, NTC10k-Pre, NTC20k and Ni1000 are also available.
