Cubic-Ruiyi Gasboard-9805 is a Portable Emissions Measurement System (PEMS) which is used to measure emissions from combustion engines in real driving. It utilizes three different PEMS modules, including PEMS-GAS for measuring the concentrations of gas emissions (CO, CO2, THC, NO, NO2), PEMS-PN for measuring particulate matter, and PEMS-EFM for measuring exhaust flow rate. As part of the basic measurements, Gasboard-9805 can also collect location data byaGPS (Global Positioning System) module. In order to record actual driving environment conditions and calculate vehicle performance, it can measure a range of environmental conditions such as atmospheric temperature, humidity and pressure. With accurate time alignment function, Gasboard-9805 can synchronize all measurement data in time under the actual driving conditions.It meets the requirements primely in RDE (real-driving emission) test and provides the total mass emissions report. Additionally, the user-friendly PC software offers fast & accurate testing data and provides easy-to-install & easy-to-use experience for users. Integrated with advanced gas analyzers, exhaust mass flow meters, weather station, Global Positioning System (GPS) and connection to the vehicle networks, Gasboard-9805 offers an advanced solution for on-board measurement that complies with the emissions testing requirements of the EU and US. It is ideally suited for on-road and off-road applications ranging from large heavy duty engines to small light-duty vehicles and off-road mobile machinery.
