Multifunctional on-wall sensors and measuring transducers, for CO2 content and air quality (VOC)
AERASGARD® ALQ-CO2-W

AERASGARD® ALQ-CO2-W

Maintenance-free on-wall sensor AERASGARD® ALQ - CO2 - W with active/switching output, automatic calibration (can be deactivated), in an impact-resistant plastic housing with quick-locking screws, optionally with/without Display, for determining the CO2 content of the air (0...2000 ppm/0...5000 ppm), the quality in three VOC sensitivity levels (low/ medium/high), the temperature (–35...+80 °C) as well as the relative air humidity (0…100 % r.H). The measuring transducer converts the measured values into a standard signal of 0 -10 V or 4...20 mA (switchable).

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.

CO2 switchable: 0...2000 / 5000 ppm
VOC: 0...100 %
