Product Overview
The KGD-WQ-503 Portable Emission Testing System (PEMS) is developed using independently researched core gas analysis technology. This advanced system measures and collects volume concentrations of air pollutants including CO, CO₂, NO, NO₂, NOₓ, and O₂, along with exhaust gas flow, environmental parameters, and OBD data.
The system features optional PN and THC measurement modules, test process guidance, automatic emission calculations, and report generation. Its modular design and portable battery (6+ hour runtime) make it ideal for non-road mobile machinery emission testing.
Key Features
- High-precision detection: Independently developed core technology for accurate measurements
- Direct NO/NO₂ measurement: Eliminates converter furnace requirements and reduces maintenance
- User-friendly operation: Includes test guidance, automatic calculations, and report generation
- Modular flexibility: GAS, PN, and THC modules can operate independently
- Extended battery life: 6+ hours of continuous operation for complete emission tests
- Standard compliance: Meets all national standard requirements
