HYGRASREG RH - 2
Mechanical room hygrostat HYGRASREG
microswitch 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. RH-2 is used for controlling and monitoring the
relative humidity in office and residential rooms, baths, labs, control cabinets, computer
rooms, etc., as minimum or maximum hygrostat. It is used in dust-free, pollutant-free,
non-aggressive air.
