Overview

The portable engine emission tester is based on ultraviolet differential absorption spectroscopy (UV-DOAS), non dispersive ultraviolet (NDUV), and non dispersive infrared (NDIR) technologies, and can simultaneously measure the volume concentrations of NO, NO2, and CO2 gases in engine exhaust. Especially suitable for emission measurement of non road diesel engines (including marine engines), non road machinery, heavy-duty diesel vehicles, and engines under real working conditions. Adopting a portable design and built-in power supply, it enables on-board (engine) measurement, making it easy to grasp the actual nitrogen oxide emission level of the engine under working conditions, and the measurement results are more valuable. Configure a projection type smoke meter to measure engine opacity smoke. PNPM detection module can be optionally selected according to customer needs (developed separately). Additional component measurements, such as CO, can be added according to customer needs.
