4. Short Notes on Non-Dispersive Infra-Red (NDIR) Analyzer

This article provides short notes on Non-Dispersive Infra-Red (NDIR) Analyzer. NDIR analyzers have been developed to monitor SO2, NOx, CO and other gases that absorb in the infra-red, including CO2 and hydrocarbons. However it is probably true to say that this is the "preferred" technique only for CO monitoring of pollutants in ambient air. The technique is of relatively low [...]
