WINSTON EFR 012 Eletronic Hygrostat
Adjustable & pre-set relative humidity setpoints.
Compact design
High switching capacity
Optical function display(LED)
DIN rail mountable
The EFR 012 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.
