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

The diesel vehicle emissions gas analyzer is a high-precision instrument specifically designed for measuring exhaust emissions from diesel engines. It uses micro-flow infrared dual-chamber sensor technology, combined with non-dispersive ultraviolet (NDUV) and non-dispersive infrared (NDIR) methods, to accurately measure key gases such as NO, NO\u2082, and CO\u2082.<\/p>\n

The system complies with the Chinese standards GB 3847-2018 (Limits and Measurement Methods for Diesel Vehicle Emissions) and JJG 688-2017 (Verification Regulation for Vehicle Emission Gas Analyzers). It offers high accuracy, low maintenance, and excellent stability, meeting the strict requirements of diesel emission testing and environmental regulation.<\/p>\n

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

The analyzer integrates multiple detection technologies for precise multi-gas analysis.<\/p>\n

NO is measured using a micro-flow infrared dual-chamber sensor, where a dual-cell structure and optical filtering compare infrared absorption signals to minimize the effects of temperature fluctuations and sensor aging.<\/p>\n

NO\u2082 is measured directly using the non-dispersive ultraviolet (NDUV) absorption method, eliminating the need for a NOx converter and simplifying the system.<\/p>\n

CO\u2082 is measured using non-dispersive infrared (NDIR) absorption, where gas concentration is determined by the degree of infrared light absorption.<\/p>\n

Advanced algorithms perform linear correction of the signals, while multi-stage processing enhances overall measurement accuracy and stability.<\/p>\n
