7878 REGULATING PRODUCT CATALOGUE - STEGO TECHNICAL DATASHEET ELECTRONIC HYGROSTAT EFR 012 > Adjustable and pre-set relative humidity > Clip fixing > Status indicator (LED) > Temperature-compensated > High switching capacity 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. TECHNICAL DATA Switch difference 5 % RH (3 % RH tolerance) at +25 C (+77 F), 50 % RH Reaction time 5 sec.
