HYGRASREG® RHT - 30Electronic HYGRASREG® RHT-30 room hygrostat and/or room thermostat with one continuous and two switching outputs, adjustable switching thresholds, with/without optional 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 is suitable for regulating and monitoring relative humidity (humidifying and dehumidifying) and/or temperature (heating and cooling) e.g. in ventilation and air conditioning ducts, laboratories, production facilities, climate test chambers, indoor swimming pools, greenhouses, etc., for humidifying and dehumidifying equipment or heating system control. The measuring transducer has been designed for exact humidity/temperature measurement. The RHT-30 uses a digital, long-term stable sensor as a measuring element. It is used in dust-free, unpolluted, non-aggressive air.
