Patented quality product (patent no. DE 10 2014 010 719.1)
Maintenance-free duct sensor
AERASGARD

KLQ-SD
with active output, automatic calibration (fixed), in a compact plastic housing with snap-on lid,
for determining the air quality in three VOC sensitivity levels (low/medium/high). The measuring transducer converts the measured values into a
standard signal of 0 -10 V.
Maintenance-free duct sensor
AERASGARD
®
KLQ-W
with active/switching output, automatic calibration (can be deactivated), in a compact plastic
housing with quick-locking screws, for determining the air quality in three VOC sensitivity levels (low/medium/high). 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 from building components,
etc. With regard to the expected air contamination, low, medium or high VOC sensitivity can be selected.
