Electronic Hygrotherm ETF012
Product Description
The electronic Hygrotherm senses the ambient temperature and relative humidity in enclosures and cabinets with electric/electronic components and turns on a heater (or alternatively, a fan) once the set point is achieved, helping to 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.
