Beim NDIRPrinzip wird die optische Transmission des Gases in einem ausgewählten Spektralbereich gemessen. Dieser wird mittels eines Bandpassfilters so festgelegt, dass er möglichst genau eine ausreichend intensive und charakteristische Absorptionsbande des Gases umschließt. Die Abbildung zeigt das am Beispiel des Kohlendioxids.

Product Review: Carbon Dioxide CO2 Meter (NDIR) ICCENTER512
