EFR012 Electronic Hygrostat

* Temperature and humidity adustable
* Optical operating display (LED)
* High switching capacity
* Clip fixing

The Electromechanical 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. The LED integrated in the adjustment knob on the active controller is lit when the connected device is in operation.
