LINKWELL is the best MFR 012 / MFR 012-2 Humidity Regulating manufacturer in China. Offering quality product to global customers
  • MFR 012 Electromachanical Hygrostat
  • MFR 012-2 Electromachanical Hygrostat
MFR 012 Electromachanical Hygrostat

Advantage:
* Adjustable relative humidity
* Easily accessible terminals
* Change-over contact
* Clip Fixing
* High switching capacity

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.
