· Bei einem VOC Sensor wird kein CO2 Wert berechnet. Es wird ein Wert angegeben der (rein vom Zahlenwert her) ein Äquivalent zum CO2 darstellt. Das wird wohl gemacht, weil man bei CO2 ein Gefühl von den zahlen hat und weiß wo festgelegte Grenzwerte liegen. Für ein BüroArbeitsplatz glaube ich beispielsweise bei 3000ppm, was meinem Gefühl nach noch ok ist. bei 4000ppm oder …
