AERASGARD KCO
Patented quality product (patent no. DE 10 2014 010 719.1)
The maintenance-free, microprocessor-controlled AERASGARD
used to detect CO content as well as gas temperature. The measurement signals are converted to standard signals of 0 -10 V.
2
The CO content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the CO
2
calibrated for standard applications such as monitoring residential rooms and conference rooms. Room ventilation on an as-needed basis, improved
well-being and customer benefit, increased comfort as well as reduced operating costs through energy conservation are just some of the benefits of
®
employing AERASGARD CO
2
A measuring system based on NDIR (non-dispersive infra-red technology) for CO
range of wavelengths of light radiated by the source is damped and absorbed by CO
the receptor.
