SV-4Q Automobile Exhaust Emission Gas Analyzer for Petrol Gasoline Car Car Automobile Exhaust Gas

SV-4Q Automobile exhaust gas analyzer for petrol gasoline car

Brief introduction

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. The analyzer introduces advanced foreign technology. It is composed of complete imported machinery cores, boasts the advantages of accuracy measurement, high endurance and speed. As an Intelligent Equipment, it is equipped with Microprocessor, LCD and Chinese language interface. Besides, it also has optional equipments such as Induction Tachometer, temperature sensor, inner Micro Printer for customers to purchase. The newly-added Storage function can detect Engine’s speed and Lubricant’s Temperature while measuring tail gas, then store and print the results
