AERASGARD RCO
The maintenance-free microprocessor-controlled AERASGARD
to detect the CO content in air within a range of 0 ppm to 2000 ppm CO
2
The measurement signals from the CO
signals of 0 -10 V. Optionally, this CO
with display or switching output.
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
pre determined breaking point for on-wall cable entry. or in enclosures made of
stainless steel (top and bottom part are of stainless steel, the lid is screwed on),
van dalism-secure version e.g. for schools, military barracks, and public buildings.
The CO content in air is determined by a two-ray NDIR sensor (non-dispersive
2
infrared technology). The detection range of this CO
for standard applications such as monitoring of residential rooms or con ference
rooms. Room ventilation on an as-needed basis, improvement of well-being and
customer benefit, increased comfort as well as a reduction of operating costs by
energy conservation are only some of the beneficial results of employing
®
AERASGARD RCO sensors.
