OBS-ONE PM - On-board Emissions Measurement

On-board Emissions Measurement System

On-board PM measurement for real-world results

OBS-ONE PM unit is the industry-leading on-board Particulate Matter (PM) measurement system. It collects PM on a filter paper, using a partial flow gravimetric sampling method, while simultaneously measuring real-time PM. A key feature of this design is the use of a venturi flow meter which enables reliable proportional sampling and accurate exhaust gas flow measurement under transient flow conditions. Combine the GAS unit and PM unit to perform certification tests on heavy duty and non-road vehicles.
