Mechanical Hygrostat MFR 012

    • 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
    • Large setting range
    • Small size
    • Simple to mount
    • High switching performance
