Duct hygrostats HYGRASREG® KHT - 30

€224.59
Tax included

Electronic HYGRASREG® KHT-30 duct hygrostat and/or duct thermostat with one continuous and two switching outputs, adjustable switching thresholds and a display for indicating actual humidity and/or actual temperature (accuracy class ±2.0% r.H.). The setpoints can be allocated to relative humidity and/or temperature. The sensor device serves to control and monitor relative humidity (humidifying and dehumidifying equipment) and/or temperature (heating and cooling systems) e.g. in ventilation and air conditioning ducts, laboratories, production facilities, climate test chambers, indoor swimming pools, greenhouses, etc.
