Mechanical Hygrostat MFR 012 1.New Style Mechanical Hygrostat 2.Large setting range 3.Small Size,Thermostat CE Cert

The electromechanical hygrostat MRF 012 is designed to control enclosure heaters so that the dew point is raised when a critical relative humidity of 65% is exceeded. In this way condensation and corrosion is effectively prevented.
