KCO2-W

AERASGARD® KCO2-W

Art.nr. 1501-3140-7301-200
EAN 4 251325 613024

Patented quality product  (patent no. DE 10 2014 010 719.1)

The maintenance-free microprocessor-controlled duct sensor AERASGARD® KCO2 - W with automatic and manual calibration, enclosure with quick-locking screws, optionally with / without display, is used for detecting the CO2 content of the air. The measurement signals are converted to standard signals of 0 -10 V or 4...20 mA.   

The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the CO2 sensor is 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® CO2 sensors. 

A measuring system based on NDIR (non-dispersive infra-red technology) for CO2 measurement consists of a light source and a receptor. A certain range of wavelengths of light radiated by the source is damped and absorbed by CO2 molecules in the measured section. This damping is detected by the receptor.
