Exhaust Gas Analyzer
A diagnostic tool that measures vehicle emission levels.
Exhaust gas analyzers detect levels of CO, CO?, HC, and NOx to assess engine combustion and emission compliance. Used during inspections and tuning, they help identify faulty sensors or catalytic converters. Calibration ensures accuracy. Data from analyzers guide engine adjustments for optimal efficiency and reduced pollution.
