HYGRASREG ® RH - 2
Mechanical room hygrostat HYGRASREG
micro switch as two-position controller with humidity sensor) working without external
voltage, with humidity measuring element made of stabilized synthetic gauze, optional
with setpoint setter for switchpoint adjustment (external or internal setting) in an
elegant enclosure made of plastic, with snap-on lid, base with 4-hole attachment for
installation on vertically or horizontally installed in-wall flush boxes, with predetermined
breaking point for on-wall cable entry. HYGRASREG
monitoring the relative humidity in office and residential rooms, baths, labs, control
cabinets, computer rooms, etc., as minimum or maximum hygrostat. It is applied in
dust-free, pollutant-free, non-aggressive air.
