AERASGARD® RLQ-SD-U

Item No. 1501-61C0-1001-200
EAN 4 251325 616360

Maintenance-free room sensor AERASGARD® 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).

Maintenance-free room sensor AERASGARD® 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.
