Kanal-Hygrothermostat HYGRASREG® KHT-30-AW LCD

Patented quality product (AOS patent no. DE 10 2015 015 941 B4)
Electronic duct hygrostat and/or duct thermostat HYGRASREG® KHT-30 (± 2.0 % RH) with two continuous and two switching outputs, configurable relay assignment (4 modes), for precise measurement of relative humidity (0...100 % RH) and temperature with 4 switchable measuring ranges (max. -35 °C/-31 °F to +80 °C/+176 °F), incl. mounting flange, with plastic sinter filter (replaceable), housing made of impact-resistant plastic with quick-locking screws, with cable gland (M12 plug connector to DIN EN 61076-2-101 on request), with display. The display can be switched from SI to imperial units via DIP switches. The measuring transducer automatically detects the required output type (Automatic Output Switching) and converts the measured variables into a standard signal of 0 -10 V or 4...20 mA.


The duct sensor is used in non-aggressive, dust-free environments. It is suitable for controlling and monitoring relative humidity (humidification and dehumidification) and/or temperature (heating and cooling), e.g. in ventilation and air conditioning ducts, laboratories, production rooms, climatic cabinets, swimming pools, greenhouses, etc., for controlling humidification and dehumidification equipment or heating control. A long-term stable, digital humidity and temperature sensor guarantees exact measurement results. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
