The electronic hygrotherm senses the ambient temperature and relative humidity in an enclosure with electric/ electronic components and turns on a heater (or alternatively a fan) at either set point, helping prevent the formation of condensation in the enclosure. Due to its wide voltage range the hygrotherm can be utilised anywhere in the world. The LED integrated in the adjustment knob on the active controller is lit when the connected device is in operation. The version with an external sensor can be installed anywhere in the control cabinet and enables precise measurement. > Temperature and humidity adjustable > Wide voltage range > Operating temperature down to -40 °C > High switching capacity > Status indicator (LED) Connection diagram Example of connection with integrated sensorHeater Hygrotherm ETF 012 Heater ELECTRONIC HYGROTHERM ETF 012 Art.
