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.
Product Features
- Adopts TDLAS patented technology, featuring high sensitivity and
strong selectivity.
- The high - temperature - resistant gas chamber design avoids the
condensation loss of NH₃, improving the measurement accuracy and
stability.
- The small - volume multi - pass reflective gas chamber design
enhances the measurement response speed.
