Outdoor humidity transmitter with display 4-20 mA

Our outdoor humidity transmitter with a current output of 4-20 mA and display has a plastic housing with quick-release screws. This device measures the humidity and optionally the temperature. Four switchable measuring ranges are available for temperature measurement. The relative humidity is recorded by a digital humidity sensor housed in a plastic sintered filter. The two-line display shows you either the humidity or the temperature in large format.

Outdoor humidity transmitter - Important assembly instructions
					Mount your outdoor transmitter at a sufficient distance from ventilation openings, windows or doors and preferably on the north wall, alternatively on the west or east wall of the building. Avoid direct sunlight and rain. Use Sun Protection if necessary. Please lay the cables downwards so that rainwater can drip off in a defined manner. Please observe the permissible ambient conditions during installation.
The device may only be used in pollutant-free, non-condensing air (< 95 % RH). The sintered filter protects the humidity sensor in outdoor and duct probes from dust, which can falsify the measurement result. Maintenance in the event of contamination is therefore important. Avoid touching the humidity element to prevent incorrect measurements.
