AERASGARD RLQ - CO
The self-calibrating microprocessor-controlled AERASGARD
detect the air quality regarding VOC and the CO
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. or in enclosures made of stainless steel (top and
bottom part are of stainless steel, the lid is screwed on), vandalism-secure version
e.g. for schools, military barracks, and public buildings. The CO
determined by a NDIR sensor (non-dispersive infrared technology). The detection
ranges of these sensors are calibrated for standard applications such as monitoring
of residential rooms or conference rooms. Room venti lation 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
alternative to choose between three sensi bility ranges for VOC monitoring by means
of jumpers, comparable to three measuring ranges: LOW for low, MEDIUM (default,
equivalent to the hitherto existing type of this device) for medium, and HIGH for high
VOC sensibility.Also three measuring ranges were introduced for CO
urement. The selection between the measuring ranges 0...2000 ppm (default, equiv-
alent to the hitherto existing type of this device), 0...5000 ppm, and 0...10000 ppm is
likewise enabled via jumpers.
