◎ High accuracy SPN10 measurement with CPC for proposed future regulations

◎ High precision and compact dimensions realized by the optimized pre-conditioning unit

◎ Improved testing efficiency with automatic zero check function (patent applied)

◎ Isopropyl alcohol as the working fluid : Safely used by saturation of a small cartridge during test preparation - no reservoir required

◎ User-friendly design mounts easily on any vehicle

Integrated Operating Platform

The OBS-ONE and other HORIBA ONE series systems employ a common user interface with future expandability. Control, monitoring and management of each emission measurement device and each module unit of OBS-ONE series can be integrated into a single controller.

Dimensions and system configurations

RDE Test with Portable Emission Measurement System (PEMS)

In 2016 the European Commission´s (EC) Member States agreed on new procedures and requirements for light-duty vehicle type approval certification introducing Portable Emission Measurement System (PEMS) for vehicle testing on the road.

Real driving emissions with RDE CoDriver

Real Driving Emission (RDE) tests confirm the results produced during an emissions test on a chassis dynamometer to ensure that vehicles meet the set limits in the real world.

Particle Measurement in the Sub-23nm Range

Concerns exist that advances in modern engine technology may contribute to large portions of solid particles at sizes smaller than 23nm. The EU Joint Research Center has confirmed this concern in several investigations.
