KGD-WQ-507 Dual - channel Direct - sampling Gas Emission Analyzer
Product Introduction
The KGD-WQ-507 Dual - channel Direct - sampling Gas Emission Analyzer combines high - precision Hydrogen Flame Ionization Detection (HFID) technology, Non - Dispersive Ultraviolet (NDUV) gas analysis technology, Chemiluminescence Detection (CLD) gas analysis technology, Non - Dispersive Infrared (NDIR) gas analysis technology, and Magnetic - Parametric Detection (MPD) technology. It simultaneously measures the volume concentrations of gases such as THC, CH₄, NOₓ, CO, CO₂, and O₂ in the raw exhaust of engine tailpipes, as well as the volume concentration of CO₂ in the EGR pipeline gas. It can provide engine manufacturers, testing institutions, and scientific research departments with a complete system testing solution for detecting and analyzing engine exhaust pollutants to meet the increasingly strict and flexible emission limits.
