The ANSED Diagnostics NOx Exhaust Gas Analyzer, No. KANE-EGA1NO, measures oxides of nitrogen (NOx) from 0-600 ppm. It is ideal for tuning gasoline engines, with or without a dynamometer, and measures true outlet NOx emissions for diesel engine diagnostics. The analyzer is designed for evaluating AdBlue/DEF and NOx reduction system performance. The EGA1NO can help identify issues related to NOx sensors, AdBlue/DEF dosing, SCR catalyst efficiency, ammonia slip, and elevated NOx feed gas levels. It may also assist in diagnosing diagnostic trouble codes (DTCs) such as P20EE and P2002.
