SV-5QG Car Exhaust Analyzer Working Conditions Exhaust Analyzer

Introduction:

SV-5QG car exhaust gas analyzer (hereinafter referred to as the instrument) uses the principle of non-divisional infrared absorption method, by microcomputer analysis, can be directly measured vehicle exhaust emissions of HC, CO and CO2 concentration; electrochemical principle of measuring exhaust In the concentration of NO and O2, and based on the measured concentration of CO, CO2, HC and O2 calculated excess air coefficient λ. The instrument imported advanced foreign technology, assembled by a complete set of imported movement, with accurate measurement, easy operation, high durability, fast detection speed and other advantages, and equipped with a microprocessor, the use of liquid crystal display, intelligent Chinese interface instrument . The instrument also equipped with other features such as inductive tachometer, temperature sensor probe and built-in mini-printer for users to choose from, while also increasing the storage function, can detect the exhaust gas at the same time detect the engine speed, lubricant temperature and storage, printing Current test result.

The instrument out of real-time testing functions, but also in accordance with national standards "GB / T 18285-2005 ignition engine exhaust emission limits and measurement methods (double idling method and simple conditions)" double idle method Of the provisions of the preparation of a double idling test conditions under the special procedures for the detection process of automatic control. Therefore, it is very convenient to measure with double idle discharge. The instrument is small, light weight, can store 500 sets of measured emissions test data, especially for roadside inspection. Testing for automotive manufacturers, motor vehicle testing stations, car repair shops and other use.
