Schabus Air quality sensor CO2 sockets warning device GX D11

After just 3 minutes of operation and the completion of the initialization phase, the first result is displayed. The concentration thresholds are based on the RKI's recommendations for school operations, with 1000 ppm for yellow and 2000 ppm for red. The CO2 warning device GX-D11 is right on trend. Increased levels of carbon dioxide in the indoor air from exhaled air are directly related to the presence of aerosols, which are carrier particles for viruses and bacteria. The GX-D11 visually and audibly reminds you to ventilate regularly to keep germ levels low and the air fresh. Especially in winter, there is no need to worry about the room getting too cold, as extensive internal and external tests have shown that the so-called rule of thumb for ventilation without CO2 monitoring is overly strict for safety reasons. LEDs in green, yellow, and red indicate air quality: green / fresh – hygienically safe, yellow / bad – hygienically questionable, red / worst – hygienically unacceptable. The CO2 warning device GX-D11 is equipped with a genuine NDIR (infrared) sensor that cannot be fooled by air purifiers, as these cannot filter CO2 from the air. CO2 not only correlates with the overall germ load in indoor spaces but also displaces oxygen at higher concentrations, thus posing a burden on the human immune system. This happens even before a person feels tired due to a decline in concentration and performance, indicating that it’s time to ensure fresh air.
