03. Non-Dispersive Infrared (NDIR) Analyzers

CAI offers two analyzer models that use Non-Dispersive Infrared (NDIR) technology to measure the concentrations of IR-absorbing gases in a sample. The 600 and ZPA models utilize paramagnetic or fuel cell technology to measure Oxygen. 

Gaz analyser 

- 700 LX NDIR/O2  – Up to 3 IR channels or 2 IR channels + O2
- ZPA NDIR/O2 – Up to 4 IR channels (including SO2, NOx) + O2

More details



CAI NDIR analyzers’ measurements are based on the infrared absorption characteristics of gases. Using a single infrared beam to measure gas concentrations, they deliver highly stable and reliable results. CAI NDIR analyzers are well-suited for a wide range of applications, including:

- Stack gases (CEM)
- Vehicle emissions
- Combustion efficiency
- Turbine/generator feedback control
- Process chemical gas analysis
- Fuel cell analysis
- Personnel safety
