AERASGARD ACO
The self-calibrating microprocessor-controlled AERASGARD
detect the CO content in air. This CO
2
without display. The measurement signals are converted into standard signals
of 0 -10 V. Optionally, this CO
switching output. The CO content in air is determined by a NDIR sensor (non-
2
dis persive infrared technology). The detection range of this CO
brated for standard applications such as monitoring of residential rooms or
conference rooms. Room ventil ation 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
