Product Detailed
MFR 012 Mechanical Hygrostat Adjustable relative humidity change-over contact,high switching capacity Easy using clip fixing

MFR 012 Mechanical Hygrostat 

1.Features:

Adjustable relative humidityChange-over contact

High switching capacityEasy usingClip 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.
