KGD - WQ - 513 Vehicle Emission Gas Analyzer (Gasoline Vehicle)
Product Introduction
The KGD - WQ - 513 Vehicle Emission Gas Analyzer (Gasoline Vehicle) detects the concentration of NO based on high - precision micro - flow infrared dual - gas - chamber sensor technology with independent intellectual property rights and an international PCT patent (PCT/CN2018100767). The sensor adopts a dual - gas - chamber structure and special filters, which solves problems such as environmental temperature instability and aging of electronic components. It measures the concentration of NO₂ based on the non - dispersive ultraviolet (NDUV) absorption method without the need for a NOₓ converter. It simultaneously detects the concentrations of HC, CO, and CO₂ in vehicle exhaust based on the principle of non - dispersive infrared (NDIR) absorption technology, and measures the concentration of O₂ using long - life electrochemistry (ECD) analysis technology, and automatically calculates and displays the air - fuel ratio.
