A 5 gas analyzer is a key diagnostic tool used by automotive technicians to assess the emission levels of internal combustion engine exhaust emissions, including carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx), oxygen (O2) and hydrocarbons (HC). The five-gas analysis helps them evaluate a vehicle’s combustion process efficiency, optimize the air-fuel ratio, and ensure compliance with federal and state environmental regulations.

These instruments can be handheld or bench-mounted and feature multiple gas sensors. The sensor inputs are calibrated to a specific reference and are connected via high-temperature silicone tubing to a water trap, filter, and oxygen sensor. The gas then passes through these components, undergoing a rapid change in temperature which causes the dew point to drop, resulting in the formation of condensation (water). The water trap function prevents water from entering the analyzer, and the filters protect the carbon monoxide sensor from acidic gases that may affect its accuracy by cross interference.
