RLQ - SD
with active output, automatic calibration (fixed), in an elegant 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 or 4...20 mA (switchable).

RLQ - W
with active/switching output, automatic calibration (can be deactivated, in an elegant plastic housing
with snap-on lid, optional with traffic light indicator (five coloured LEDs), 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.
