MFR 012 Mechanical Hygrostat
Efficient condensation control
Adjustable relative humidity range
High switching capacity
DIN rail mountable
The MFR 012 electromechanical hygrostat is designed to control the relative humidity inside
enclosures. When connected to an enclosure heater (dehumidifier), it will energize the heater
at the humidity set point in order to raise the dew point. This helps prevent damage and mal-
function of electronic components caused by condensation and corrosion.
