Mechanical room hygrostat HYGRASREG® RH - 2 with switching output (with single-pole microswitch, as 2-point controller with humidity sensor).

The humidity transmitter works without external voltage, with a humidity measuring element made of stabilized plastic fabric, optionally with setpoint adjuster for setting the switching points (external or internal setting). It has an attractive plastic housing with snap-on cover, lower part with 4-hole fastening, for mounting on vertically or horizontally installed flush-mounted boxes, with predetermined breaking point for surface-mounted connection.
