Gasoline Engine Exhaust Gas Analyzer Qrotech QRO-402 for Motorcycles
1. Key Features
- Analysis of 4 main exhaust gases: Measures CO, HC, CO₂, and O₂, with an optional NOx measurement, supporting the calculation of λ (air-fuel ratio) and AFR (air-to-fuel ratio).
- Advanced measurement technology: Utilizes Non-Dispersive Infrared (NDIR) for CO, HC, CO₂, and electrochemical sensors for O₂ and NOx.
- Fast response time: Results displayed within 10 seconds, optimizing testing efficiency.
- Compact and portable design: Lightweight and medium-sized, ideal for inspection centers or repair workshops.
- Compatibility with multiple fuels: Supports emissions testing for engines using gasoline, LPG, CNG, or alcohol-based fuels.
