Product Overview
The Automotive Emissions Gas Analyzer (Gasoline Vehicles) utilizes proprietary high-precision microflow infrared dual-chamber sensor technology to accurately measure the concentration of gases such as NO, NO₂, HC, CO, CO₂, and O₂ in gasoline vehicle emissions. This instrument integrates non-dispersive infrared (NDIR) and non-dispersive ultraviolet (NDUV) absorption technology, along with long-life electrochemical (ECD) analysis technology, ensuring high-precision measurements and automatic calculation and display of the air-fuel ratio. It complies with the "Gasoline Vehicle Pollutant Emission Limits and Measurement Methods" (GB 18285-2018) and "Automotive Emissions Gas Tester Calibration Regulations" (JJG 688-2017), meeting the accuracy requirements for Class 00. This makes it an ideal choice for gasoline vehicle emission testing.
