AERASGARD KLQ - SD / KLQ - W
Patented quality product (patent no. DE 10 2014 010 719.1)
Maintenance-free duct sensor AERASGARD
determining the air quality (0...100 % VOC). The measuring transducer converts the measured values into a standard signal of 0 -10 V.
Maintenance-free duct sensor AERASGARD
locking screws, for determining the air quality (0...100 % VOC). 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.
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 etc. With regard to the
expected air contamination, low, medium or high VOC sensitivity can be selected. As an alternative, use IAQ categories (from excellent to unhealthy)
following the guidelines of the German Federal Environmental Agency to assess the room air.
