HiYi CE Portable Automobile Exhaust Gas Analyzer with 0-4000×10⁻⁶ NO Detection and 0-18.0% CO2 Measurement Range
The HiYi CE Portable Automobile Exhaust Gas Analyzer is a professional-grade instrument developed according to GB3847-2018 national standards for precise measurement of NO, NO2, and CO2 concentrations in motor vehicle engine exhaust gases.
This comprehensive analyzer integrates gas pretreatment, CO2 infrared technology, NO/NO2 ultraviolet technology, calibration, detection, display, and communication transmission units into a single portable device.
| Parameter | Measurement Range | Resolution |
|---|---|---|
| CO2 Concentration | 0-18.0% | 0.01% |
| NO Concentration | 0-4000×10⁻⁶ | 1×10⁻⁶ |
| NO2 Concentration | 0-1000×10⁻⁶ | 1×10⁻⁶ |
| Oil Temperature | 0-150°C | 0.1°C |
| Engine Speed | 0-999,999 rpm | - |
Preheating time: ≤30 minutes | Detection platforms: NDIR for CO2, UVDOAS for NO/NO2
- Ultraviolet differential absorption spectroscopy for simultaneous NO and NO2 measurement without water interference
- Direct optical NO2 measurement eliminates traditional converter efficiency degradation over time
- Rapid response time under 3 seconds for both NO and NO2 detection
- Android-based platform with intuitive human-computer interface and intelligent control
- Comprehensive interface connectivity for oil temperature, rotational speed, ambient temperature, humidity, and pressure parameters
This portable analyzer is widely used for road inspection and spot-check by environmental protection departments, annual vehicle inspection lines, rapid exhaust purification device inspection, automotive research in educational institutions, automobile manufacturing, and 4S maintenance shops.
