Description
Duct air quality sensors/ controllers (VOC)
AERASGARD® KLQ-W
Patented quality product (patent no. DE 10 2014 010 719.1)
Maintenance-free AERASGARD® KLQ-SD duct air quality measuring transducer with active output, automatic calibration, in a compact plastic housing with snap-on cover, for determining the air quality (0…100% VOC). The transmitter converts the measured values into a standard signal of 0-10 V.
Maintenance-free AERASGARD® KLQ-W durct air quality measuring transducer with active/switching output, automatic calibration, in a compact plastic housing with quick-locking screws, for determining the air quality (0…100% VOC). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).

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.
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 etc. With regard to the expected air contamination, low, medium or high VOC sensitivity can be selected. As an alternative, use IAQ categories to assess the room air (from excellent to unhealthy) following the guidelines of the German Federal Environmental Agency.
