Electronic Hygrostat EFR 012 Series
- Adjustable and pre-set relative humidity
- Optical operating display (LED)
- High switching capacity
- Clip fixing
- Temperature-compensated
The electronic hygrostat senses the relative humidity in an enclosure with electric / electronic components and turns on a heater at the set point, helping prevent the formation of condensation in the enclosure. The LED integrated in the adjustment knob is lit when the connected heater is in operation.
