Mechanical Hygrostat MFR 012
●Adjustable relative humidity
●Change-ove r Contact
●High switching capacity
●Easily accessible te rminals
●Clip fixinq
The electromechanical hygrostat MRF 012 is designed to control enclosure heaters sothat the dew point is raised when a critical relative humidity of 65%is exceeded.
In thisway condensation and corrosion is effectively prevented.
