AERASGARD® KTM-CO2-SD-U

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

Maintenance-free duct sensor AERASGARD® KTM - CO2 - SD with active output, automatic calibration (fixed setting), in an impact-resistant plastic housing with quick-locking screws, for determining the CO2 content of the air (0...2000 ppm / 0...5000 ppm) and the temperature (-35...+80 °C). The measuring transducer converts the measured variables into a standard signal of 0-10 V.

Air quality transmitters are used in offices, hotels, conference rooms, apartments, stores, etc. and are used to evaluate the indoor climate. This enables energy-saving, needs-based room ventilation and thus a reduction in operating costs and an increase in well-being.




A long-term stable, digital humidity and temperature sensor guarantees precise measurement results.

The CO2 measurement is carried out by means of an optical NDIR sensor (non-dispersive infrared technology). The detection range is calibrated for standard applications such as residential and conference room monitoring.

The air quality is measured with a VOC sensor (mixed gas sensor for volatile organic substances). This determines the pollution of the room air by contaminated gases such as cigarette smoke, body vapors, breathing air, solvent vapors, emissions from parts of the building, etc. A low, medium or high VOC sensitivity can be set for the expected air contamination. .
