The HY-5100 series automobile emission gas analyzers utilize proprietary ultraviolet absorption spectrum technology for NO and NO2 concentration measurement, combined with NDIR principle for HC, CO, CO2 analysis, and long-life ECD technology for O2 sensing.

• Self-developed non-spectral UV and infrared technology for superior accuracy
• Direct NO, NO2, NOx measurement without NOx converter requirement
• Multi-stage filtration system extends operational lifespan
• Modular sensor design simplifies maintenance and service
• Automatic temperature and pressure compensation for precise readings
• Integrated ports for oil temperature and tachometer connections
• Advanced signal linear correction software
• Excellent stability and strong anti-interference capabilities

This analyzer automatically calculates and displays fuel ratio while supporting testing based on user-specified operating conditions, including steady-state and working condition tests. The modular core gas sensors feature high integration and low maintenance requirements, suitable for high-humidity, low-humidity, and low-concentration gas detection environments.
