hygrostat

Adjustable relative humidity Change-over contact High switching capacity Easily accessible terminals Clip fixing 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.
