Patented quality product, patent no. DE 10 2014 010 719.1 (FLOW), DE 10 2015 015 941 B4 (AOS)


Maintenance-free duct sensor AERASGARD® KCO2-AW with active/switching output, automatic calibration
(can be switched off), in impact-resistant plastic housing with quick-release screws, incl. mounting flange, optionally with/without display, for determining the CO2 content of the air (0..2000 ppm / 0..5000 ppm). Mounting flange, optionally
with/without display, for determining the CO2 content of the air (0...2000 ppm / 0...5000 ppm). The measuring transducer automatically recognizes the required output type (Automatic Output Switching) and converts the measured variables into a standard signal of 0 -10 V or 4...20 mA.


The sensor is used in offices, hotels, conference rooms, apartments, stores, etc. and is used to evaluate the room climate. This enables energy-saving, needs-based room ventilation and thus a reduction in operating costs and an increase in well-being. One sensor per 30 m² of room area is recommended.

CO2 measurement is carried out using a photoacoustic NDIR sensor (non-dispersive infrared technology). The detection range is calibrated for standard applications such as living room and meeting room monitoring. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
