AERASGARD RCO
The self-calibrating microprocessor-controlled AERASGARD
detect the CO content in air within a range of 0 ppm to 2000 ppm CO

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 predetermined breaking point for on-wall ca-
ble 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
mined by a NDIR sensor (non-dispersive infrared technology). The detection
range of this CO sensor is calibrated for standard applications such as moni-
2
toring 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
