Mechanical Hygrostat



MechanicalHygrostat

Description
The electromechanical hygrostat is specially designed to control enclosureheaters so that the dew point is raised when a critical relative humidity of65% is exceeded. Thereby it can effectively prevent condensation and corrosion.

Features
1. Adjustable relative humidity
2. Change-over contact
3. High switching capacity
4. Easily accessible terminals
5. Clip fixing
