CAI offers two analyzer models that use Non-Dispersive Infrared (NDIR) technology to measure the concentrations of IR-absorbing gases in a sample. The 700 and ZPA models utilize paramagnetic or fuel cell technology to measure Oxygen.

• 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

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
