KGD - WQ - 510 Motor Vehicle Brake Emission Testing System
Product Introduction
The KGD - WQ - 510 Motor Vehicle Brake Emission Testing System is a comprehensive solution specifically designed for the standardized testing of motor vehicle brake particle emissions. It is composed of an air duct control system, a particle sampling system, a particle number analysis system, an inertial brake dynamometer, and a main control system. The main test items include PM2.5, PM10, SPN, and TPN, which can meet the certification test requirements of the Euro 7 emission standard and related research and development test needs..
