Product Details
KGD-WQ-509Engine Exhaust Particle Number Analysis System
Product Introduction
The Engine Exhaust Particle Number Analysis System can continuously
measure the number concentration of solid particles in engine
exhaust gas online. It can be combined with a full - flow dilution
system or a partial - flow dilution system and is used for
engine/vehicle certification tests in accordance with the latest
regulations. It can also directly measure exhaust gas from the
exhaust pipe for research and development tests of engines or after
- treatment devices.
Product Features
- High - precision primary and secondary dilution
- High - performance VPR (Volatile Particle Remover) device
- High - precision CPC (Condensation Particle Counter)
- Minimum particle size limit can be extended to 10nm
