AC220V BTMFR012 Mechanical Hygrostat
1.Hygrostat Key Features
- Adjustable relative humidity
- Change-over contact
- High switching capacity
- Easily accessible terminals
- Clip fixing
2. Hygrostat Instructions
The electromechanical hygrostat MRF012 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 if effectively prevented.
