HYGRASREG AH - 30
Electronic on-wall hygrostats and humidity sensors HYGRASREG
optional with or without display indicating the actual humidity, accuracy class ± 3 % r. H. They are used to control and monitor the relative humidity,
e.g. in venti lation and air conditioning ducts, laboratories, production facilities, climatic test cabinets, indoor swimming pools, greenhouses, etc. to control
humidifying and dehumidifying equipment. These measuring transducers are designed for exact humidity measurement. HYGRASREG
long-term stable sensor as measuring element for humidity measurement. Applications in dust-free, pollutant-free, non-aggressive air.
