EFR012 ELECTRONIC HYGROSTAT
-
- Adjustable and pre-set relative humidity
- Optical operating display(LED)
- High switching capacity
- Clip fixing
- Temperature-compensated
The EFR012 electronic hygrostat senses the relative humidity in an enclosure and turns on a heater at the set point, helping prevent the formation of condensation in the enclosure. The integrated LED is lit when the connected device is in operation.
