Automobile Exhaust Analyzer BK-EA500 (CAT#: STEM-OEM-0324-ZJF)

These instruments are used for measuring the concentration of gases emitted from vehicle exhaust systems. They are essential tools in automotive inspection, emissions testing, and environmental monitoring, providing accurate analysis of pollutants to ensure regulatory compliance and reduce environmental impact.

Measurement Range:
- HC: 0~10000×10⁻⁶ (ppm) vol
- CO: 0~10×10⁻² (%) vol
- CO₂: 0~20×10⁻² (%) vol
- O₂: 0~25×10⁻² (%) vol
- NOx: 0~5000×10⁻⁶ (ppm) vol
- λ: 0.50~3.00
- COcor: 0~10×10⁻² (%) vol
Speed Range: 0~9990 rpm
