AERASGARD® RTM-CO2-SD-U

Item No. 1501-61B2-1001-200
EAN 4 251325 616377

Maintenance-free room sensor AERASGARD® RTM - CO2 - SD with active output, automatic calibration (fixed), in an elegant plastic housing with snap-on lid, for determining the CO2 content of the air (0...2000 ppm) and the temperature (0...+50°C). The measuring transducer converts the measured values into a standard signal of 0 -10 V.

The sensor 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 exact measurement results.
The CO2 measurement is performed using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as monitoring residential rooms and conference rooms.

The air quality is detected by a VOC sensor (mixed gas sensor for volatile organic substances). This sensor determines the loading of the room air due to contaminated gases such as cigarette smoke, body perspiration, exhaled breathing air, solvent vapours, emissions from building components, etc. With regard to the expected air contamination, low, medium or high VOC sensitivity can be selected.
