KGD-WQ-503 Portable Emission Testing System (PEMS)
Product Introduction
KGD-WQ-503 is a portable emission testing system developed based on independently researched and developed core gas analysis technology. It can measure or collect the volume concentrations of air pollutants such as CO, CO₂, NO, NO₂, NOₓ, and O₂, exhaust gas flow, navigation system data, environmental temperature and humidity, atmospheric pressure, OBD parameters, etc. It can be optionally equipped with PN and THC measurement modules, and has functions such as test process guidance, automatic calculation of total emissions, and export of test reports. The product adopts a modular design, and the portable battery supports a battery life of more than 6 hours, meeting the on-board emission detection requirements for non-road mobile machinery.
