On-board Emissions Measurement System

Total System for Regulation Compliance and Engine/Vehicle R&D

OBS-ONE is the latest Portable Emissions Measurement System designed for engine/vehicle certification under real road conditions.
It measures concentrations of emissions (CO, CO2, THC, NOx, NO2), particulate matter, air-to-fuel ratio, exhaust flow rate, GPS data, environmental conditions (atmospheric temperature, humidity and pressure) and calculates mass emissions.
OBS-ONE features the highly adaptable, intelligent operating platform called “HORIBA ONE PLATFORM” which integrates other ONE series product data and optimizes test cell operation.

HORIBA has developed broad emission test applications for certification and engine/vehicle R&D, such as simulating a real-world driving event in the test cell with the Test Automation System-STARS. This simulation requires data combined from the OBS-ONE and a drive recorder.

OBS-ONE GS - One PlatformIntegrated Operation Software “HORIBA ONE PLATFORM”

Integrated Device Management Controller (DMC) with HORIBA ONE series products

The newly developed software for the OBS-ONE is integrated with the same operating platform as the MEXA-ONE, CVS-ONE and other devices. The intuitive, ergonomic design of the new software platform makes system operation easier. System control and a complete system view of other measurement devices are available from one single display. User support for system operation such as maintenance, alarms, and message functions has been further enhanced.

・Future expandability of PN counting and additional pollutant measurement, etc.
・User-friendly screen configuration and layout offer both measurement efficiency and convenience

R&D for Engine, Powertrain and Chassis

Achieving real-world simulation in the test lab

Test Lab x Real-world

OBS-ONE provides real driving emission test as well as real driving simulation in the test lab by utilizing STARS.
This comprehensive solution ensures accurate emissions data from both real-road and laboratory testing conditions.

RDE Test with Portable Emission Measurement System (PEMS)
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 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.
RDE Testing for Non-Road Mobile Machinery (NRMM)
RDE Testing for Non-Road Mobile Machinery (NRMM)
After the introduction of Real Driving Emission (RDE) tests for light- and heavy-duty vehicles, focus is now also shifting to the area of non-road mobile machinery (NRMM).
