Operating Environment-Friendly KGD WQ 501 Engine Emission Testing System for Accurate Results
Product Overview
The KGD WQ 501 Engine Emission Testing System is an integrated solution designed for precise measurement of conventional gas components (THC, CH4, NOx, CO2, CO, and O2) in full-flow dilution or raw exhaust emission tests. This comprehensive system is ideal for laboratory research, development, and certification testing of various engine types and fuels.
Key Features
- Incorporates patented gas sensing technologies (NDIR, NDUV, CLD, HFID) with complete lifecycle support
- Wide measurement range accommodates all laboratory emission test scenarios, including ultra-low emission levels
- High accuracy and rapid response for precise continuous online measurement of both diluted and raw exhaust
- Optional multi-channel sampling unit for flexible multi-point exhaust pipe sampling and EGR rate measurement
