Our outdoor humidity and temperature sensors are designed to measure relative humidity, absolute humidity, enthalpy and dew point and temperature in outdoor areas, plant rooms, cold stores, greenhouses, production plants and warehouses.


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

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

Our PT100 and PT1000 sensor range is optional with high accuracy sensor elements conforming to class A and class 1/4 DIN IEC60751.
