The electronic duct hygrostat RKF/M measures the relative humidity 0...100% r.H. in the ambient air by a capacitive sensor. For further processing, it provides a change-over contact whose switching threshold 5...95% r.H. can be adjusted by a potentiometer. The hygrostat has a 2-digit LED display to show the relative humidity and the set threshold. If the threshold is exceeded, the relay is activated and the display flashes. The humidity sensor is protected against contamination by a screw-sintered filter.
