OMEGA MFR012 Mechanical Hygrostat
- Adjustable Relative
- Humidity Range
- High Switching Capacity
- DIN Rail Mountable
The MFR012 is designed to control the relative air humidity inside of
enclosures. When connected to an enclosure heater,
(de-humidifier), it will turn the heater on at the set humidity level in order
to raise the dew point. This helps prevent damage and malfunction of
electronic components caused by condensation and corrosion. The MFR012 can
also be used to control cooling fans, warning lights or other devices.
