SV-4Q automobile exhaust gas analyzer
SV-4Q automobile exhaust gas analyzer, (hereinafter referred to as the analyzer) may,in accordance with non-light-disguising infrared absorption method, via micro-computer analysis, directly measure the thickness of HC, CO and CO2in the exhaust gas of vehicles and inspect the density of O2via Electrochemical sensor so as to calculate excess air coefficient λ.
