Connecting to an enclosure heater (dehumidifier), Omega Engineering’s MFR012 Series mechanical hygrostats are designed to control the relative air humidity inside of enclosures. The CE-compliant units activate the heater at the set humidity level in order to raise the dew point to help prevent damage and malfunction of electronic components caused by condensation and corrosion. The DIN rail-mountable devices can also be used to control cooling fans and warning lights. Pricing starts at $77.
