Product Overview
The KGD-WQ-512 Vehicle Emission Gas Analyzer (Diesel Vehicle) detects NO concentration using high-precision micro-flow infrared dual-gas-chamber sensor technology with patented design (PCT/CN2018100767). It measures NO₂ via non-dispersive ultraviolet (NDUV) absorption without requiring a NOₓ converter, and simultaneously detects CO₂ concentration using non-dispersive infrared (NDIR) absorption technology.
Key Features
- Compatible with Gasboard-6000 transmissive smoke meter for exhaust opacity measurement
- Direct measurement of NO and NO₂ without NOₓ converter - compact design with minimal maintenance
- High accuracy, excellent stability, strong anti-interference capability, and moisture resistance
- Multi-stage filtration system for enhanced durability
- Advanced software algorithm with linear correction for gas concentration signals and interfaces for oil temperature/rotational speed
