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.
The MFR 012 can also be used to control cooling fans, warning lights or other devices.
