Product Description:
Mechanical Hygrostat MFR 012
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 preven
