KGD WQ 513 Gasoline Vehicle Emission Gas Analyzer With 30min Pre-heating Time And 150W Power Supply

The KGD-WQ-513 Vehicle Emission Gas Analyzer detects NO concentration using high-precision micro-flow infrared dual-gas-chamber sensor technology with independent intellectual property rights and an international PCT patent (PCT/CN2018100767). The sensor's dual-gas-chamber structure and special filters solve problems like environmental temperature instability and electronic component aging.

This analyzer measures NO₂ concentration using non-dispersive ultraviolet (NDUV) absorption without requiring a NOₓ converter. It simultaneously detects HC, CO, and CO₂ concentrations in vehicle exhaust using non-dispersive infrared (NDIR) absorption technology, and measures O₂ concentration using long-life electrochemistry (ECD) analysis technology, automatically calculating and displaying the air-fuel ratio.

• Direct measurement of NO and NO₂ without NOₓ converter - compact structure with minimal maintenance
• High measurement accuracy with excellent stability and strong anti-interference capability
• Multi-stage filtration system for enhanced durability
• Advanced software algorithm for linear correction of gas concentration signals
• Automatic temperature and pressure compensation with interfaces for oil temperature and rotational speed
