HYGRASREG KH - 40 ⁄ AH - 40
Electronic hygrostat and humidity sensor HYGRASREG
displaying ACTUAL humidity (accuracy class ± 3 % r.H.) and for setting the target humidity.
It is suitable for controlling and monitoring the relative air humidity, e.g. in ventilation and air conditioning ducts, laboratories, production rooms,
climatic exposure test cabinets, swimming pools, greenhouses etc., for controlling humidifying and dehumidifying facilities. The measuring transducers
are designed for exact detection of humidity. The KH - 40 ⁄ AH - 40 uses a digital, long-term stable sensor as a measuring element for measuring
humidity. It is used in dust-free, unpolluted, non-aggressive air.

two-line display with illumination, cutout approx. 36 x15 mm (W x H),
for displaying actual humidit and for setting the target humidity
The 1st line of the display shows the relative humidity.
The 2nd line shows on the left side the information regarding the switching status of the relay (as a circuit),
as well as the switching value readout in % r.H. on the right side (adjustable using the set potentiometer).
○ Circuit, empty = relay in idle state
● Circuit, full = relay energised
The relay output is triggered (contact 13 -11 closed)
if the humidity switchpoint is not reached and opens (contact 12 -11 closed)
in the event of a fault (power failure, condensation)
LED short pulses = relay active → switchpoint not reached
LED long pulses = relay inactive → switchpoint exceeded
