Product Description:
Electronic Hygrostat EFR 012
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
