SW-5Q automobile exhaust gas analyzer, 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 NO and 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.
Besides detecting functions, its computer programs on detection under Two-speed Idle, written by us according to limits and measurement methods for exhaust pollutants from vehicles equipped ignition engine under two-speed idle conditions and simple driving mode conditions, can control the process of detection automatically. So it's convenient to use. The analyzer has small size, light weight, storage of 500 groups' data of exhaust gas measurement. Particularly it is suitable for check along the road. It's utilized for auto-manufacturing factories, vehicle inspection stations and garages.
