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 set at 1000 ppm for yellow and 2000 ppm for red, in line with the recommendations of the RKI for school operations. The CO2 warning device GX-D11 is timely and relevant. Increased levels of carbon dioxide in indoor air from exhaled breath are directly linked to the presence of aerosols, which carry viruses and bacteria. The GX-D11 visually and audibly reminds you to ventilate regularly to keep germ levels low and the air fresh. Particularly in winter, there is no need to fear that the room will become 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. LEDs in green, yellow, and red indicate air quality: green / fresh – hygienically safe, yellow / bad – hygienically concerning, red / worst – hygienically unacceptable. The CO2 warning device GX-D11 features a genuine NDIR (infrared) sensor, which cannot be fooled by air purifiers, as they do not filter CO2 from the air. CO2 not only correlates with the overall germ load in indoor spaces but also displaces oxygen at higher concentrations, posing a burden on the human immune system. This occurs even before a person feels fatigued or notices a decline in concentration and performance, indicating that it is time to ensure fresh air.
