Multifunctional on-wall sensors and measuring transducers, for temperature and CO2 content AERASGARD® ATM-CO2 - SD
Maintenance-free AERASGARD® ATM - CO2 - SD on-wall air climate transmitter with active output, automatic calibration (fixed), 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 values into a standard signal of 0-10 V.

The sensor device is used in offices, hotels, convention centres, apartments, shops, etc. for the purpose of evaluating the indoor climate. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being.

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

The CO2 content is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as the monitoring of residential and conference rooms.
The air quality is detected by a VOC sensor (mixed gas sensor for volatile organic substances). This sensor determines the load of contaminated gases in the room air, such as from cigarette smoke, body perspiration, exhaled breathing air, solvent vapours, emissions from building components, etc. Low, medium or high VOC sensitivity can be selected depending on the expected air contamination.
