Overview
Gasboard-9806 is a brake particulate emission measurement system for Euro 7 (EU 2024/1257), UN GTR-24 and CARB requirements, measuring PM10, PM2.5 and particle number (SPN10, TPN10). It uses CPC counting, CFD-optimized sampling and dedicated software that runs the WLTP brake cycle automatically and generates GTR 24 reports.
Key Features
- Employs advanced Condensation Particle Counting (CPC) technology for particle-number measurement, ensuring high detection sensitivity, accuracy, and repeatability.
- Applies advanced fluid-dynamics simulation for system design and optimization, reducing particle loss and improving aerosol mixing uniformity at sampling points.
- Supports compliance with new international brake emission standards, including UN GTR No. 24 and Euro 7, providing standardized testing capability for certification and conformity-of-production assessments.
- Performs fully automated execution of the WLTP brake test cycle through dedicated software, providing UN GTR No. 24–compliant test reports.
- Demonstrates proven reliability through extensive laboratory validation, ensuring stable operation and consistent measurement accuracy over long-term use.
