Product Overview<\/b><\/strong><\/h3>\n

The ultraviolet (UV) NOx emission analyzer is a high-precision instrument designed for measuring NO and NO\u2082 in vehicle exhaust. It uses ultraviolet absorption spectroscopy combined with proprietary high-precision algorithms and a direct-flow short gas chamber design to achieve accurate and stable NOx measurements.<\/p>\n

The analyzer meets the 00-level accuracy requirements of GB 3847 and GB 18285 standards, offers excellent anti-interference capability, and has a very low detection limit. It is an essential tool for vehicle emission testing and environmental monitoring.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The analyzer measures NO and NO\u2082 based on UV absorption spectroscopy. Exhaust gases pass through a direct-flow short gas chamber, where NO and NO\u2082 absorb light at specific UV wavelengths. Optical sensors detect the absorption intensity, and internal algorithms convert this data into accurate gas concentrations.<\/p>\n

The system minimizes the impact of sampling flow variations on measurements, incorporates automatic zeroing to eliminate background interference, and features self-diagnostic functions to ensure long-term stable operation.<\/p>\n

Key Features<\/b><\/strong><\/h3>\n
    \n
  • Advanced UV Absorption Technology<\/strong>: Minimizes cross-interference from other gases, enhancing measurement accuracy.<\/li>\n
  • High Anti-Interference Capability<\/strong>: Exhaust flow variations have negligible effect on NO and NO\u2082 readings, ensuring reliable measurements in complex conditions.<\/li>\n
  • Low Detection Limit<\/strong>: Suitable for precise monitoring of low-emission vehicle exhaust.<\/li>\n
  • Automatic Zeroing<\/strong>: Built-in air zeroing pump ensures accurate and reliable results for each test.<\/li>\n

    Applications<\/b><\/strong><\/h3>\n
      \n
    • Vehicle Emission Testing<\/strong>: Precisely measures NO and NO\u2082 concentrations at automotive emission testing stations to ensure compliance with environmental standards.<\/li>\n
    • Environmental Monitoring & Regulation<\/strong>: Used by environmental agencies and monitoring institutions to regularly assess vehicle emissions and control air pollution.<\/li>\n
    • Vehicle Compliance Evaluation<\/strong>: Supports emissions testing during vehicle inspections, production, and enforcement of environmental standards.<\/li>\n
    • Environmental Research<\/strong>: Provides accurate exhaust emission data for research institutions, supporting emissions reduction technologies and environmental studies.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"[tp_attributes num_attributes=\"2\"]\n

      The Ultraviolet NOx Emission Analyzer is a high\u2011precision instrument designed for real\u2011time measurement of nitrogen oxides (NO, NO\u2082, and total NOx) in vehicle exhaust, industrial emissions, and environmental monitoring applications. Using advanced ultraviolet absorption spectroscopy, it provides highly sensitive and selective detection with fast response and excellent stability. The analyzer minimizes cross\u2011interference from other gases, ensuring accurate results even in complex exhaust streams. With intelligent calibration, automatic temperature and pressure compensation, digital data logging, and robust anti\u2011corrosion design, it is ideal for regulatory compliance testing, engine development, laboratory research, and continuous emissions monitoring. Its high reliability and low maintenance requirements make it a preferred solution for precise NOx measurement.<\/p>\n
