KGD - WQ - 506 Laser Spectroscopy Engine Emission Analysis System
Product Introduction
The KGD - WQ - 506 Laser Spectroscopy Engine Emission Analysis System is integrated with a Tunable Diode Laser Absorption Spectroscopy (TDLAS) high - temperature sensor module. It can dynamically and accurately measure the volume concentrations of NH₃ and N₂O in engine exhaust samples under high - temperature (190°C) and high - humidity conditions. It is suitable for type - approval tests and related research and development tests that comply with current major vehicle emission standards and the Euro 7 emission standard.
