Room humidity transmitter with display 4-20 mA

Our room humidity transmitter with a current output of 4-20 mA and display can be easily installed using screws. This device measures the humidity and optionally the temperature. The room humidity transmitter with 4-20 mA display is ideal for the precise measurement of humidity and temperature in indoor areas such as offices, supermarkets and schools. The two-line display shows you either the humidity or the temperature in large format.

Room humidity transmitter - Important assembly instructions
					For precise measurement of room temperature and humidity, it is crucial to take into account both the temperature dynamics and the humidity dynamics in the room. Air circulation should only take place through the openings in the housing cover. Therefore, the transmitter should be installed away from objects or obstacles that could block air movement. Also avoid uncontrolled air currents (draughts) by installing the transmitter near doors or windows. The transmitter should also not be installed on the colder outside wall to prevent measurement inaccuracies.
The device should only be used in pollutant-free, non-condensing air (< 95 % RH).
