Detailed Product Description

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 CO₂ in the exhaust gas of vehicles and inspect the density of O₂ via  Electrochemical sensor so as to calculate excess air coefficient λ.
