Duct air quality (VOC) and CO2 sensors AERASGARD® KLQ-CO2-W LCD

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

Maintenance-free duct sensor AERASGARD® KLQ-SD with active output, automatic calibration (fixed setting), in a compact plastic housing with snap-on lid, for determining the air quality or air quality in three VOC sensitivity levels (low/medium/high). The measuring transducer converts the measured variables into a standard signal of 0-10 V.

Maintenance-free duct sensor AERASGARD® KLQ-W with active/switching output, automatic calibration (can be switched off), in a compact plastic housing with quick-release screws, for determining the air quality or air quality in three VOC sensitivity levels (low/medium/high). The measuring transducer converts the measured variables into a standard signal of 0-10 V or 4...20 mA (switchable).



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.

The air quality is measured by means of 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 buildings, etc. A low, medium or high VOC sensitivity can be set for the expected air contamination.
