MFR012 MECHANICAL HYGROSTAT
-
- Adjustable relative humidity
- Change-over contact
- High switching capacity
- Clip fixing
- Easily accessible terminals
The MFR012 electro mechanical hygrostat is designed to control the relative humidity inside enclosures. When connected to an enclosure heater (dehumidifier), it will energize the heater at the humidity set point in order to raise the dew point. This helps prevent damage and malfunction of electronic components caused by condensation and corrosion.¹ The MFR 012 can also be used to control cooling fans, warning lights or other devices.
¹ The critical relative humidity level for most components is 65%. Above 65% RH, condensation can form and cause malfunctions
of electronic equipment. Long term, this can lead to corrosion and permanent damage of electronic components and systems.Technical Data
