Description
AERASGARD®
Maintenance-free, multifunctional AERASGARD® RFTM - PS - CO2 - W room air quality measuring transducer with active/switching output, automatic calibration, in an elegant plastic housing with snap-on cover, base with 4-hole attachment, optionally with/without display, for detecting air humidity (0...100% RH), temperature (0...+50°C), particulate matter (PM) (0...50/100/300/500 μg/m3) and CO2 content (0...2000 / 5000 ppm). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).
The multifunctional sensor device is ideal for effectively monitoring and controlling the entire indoor climate with just one device. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. It is used in offices, hotels, convention centres, apartments, shops, etc.
A long-term stable, digital humidity and temperature sensor guarantees precise measuring results. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). An optical particulate sensor precisely detects particulate matter (PM) of size categories 0.3 to 10 micrometres. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
