On-Board Systems
OBS-ONE series - HORIBA, Ltd.
HORIBA developed the OBS-ONE series on-board emission measurement system in response to new requirements for exhaust emissions measurement from vehicles being driven on public roads (Portable Emissions Measurement Systems - PEMS). This development has been made possible by reducing the dimensions and power consumption of laboratory grade analyzers and ensuring that the system components have excellent vibration resistance. The OBS-ONE series continuously measures not only the concentration of CO, CO2, THC and NOx, but also measures exhaust fl ow rate and A/F ratio to calculate mass emission and fuel economy.

On-board Emissions Measurement System
OBS-ONE PM unit
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.
