OBS-ONE GS Portable Emissions Measurement System

Sistema de Medição de Emissões a Bordo

Portable Emissions Measurement System for Real-World Testing

Obtaining valid emissions results under real-world driving conditions requires more than measuring exhaust gas concentrations. Engineers must coordinate exhaust-flow, vehicle, GPS and environmental data while monitoring test validity throughout the journey.

The OBS-ONE GS Unit is a Portable Emissions Measurement System (PEMS) for measuring gaseous emissions from light- and heavy-duty vehicles under real-road conditions. It measures CO, CO₂, NOx, NO₂ and, in selected configurations, THC while collecting exhaust-flow, vehicle-speed, GPS and environmental data to calculate mass emissions.

Designed for regulatory testing and engine and vehicle research and development, the system guides users through test preparation, quality checks, measurement, real-time validation and post-processing. Its modular configuration can be expanded with compatible OBS-ONE particle-measurement units and other sensors according to the testing application.

As part of HORIBA ONE PLATFORM, OBS-ONE provides a common operating environment for compatible HORIBA measurement systems. Centralized device control, system status, maintenance information, alarms and measurement data help simplify operation across real-road and laboratory testing.

OBS-ONE data can also be combined with drive-recording information and HORIBA’s STARS test automation system to reproduce real-world driving events in the laboratory, supporting repeatable engine, powertrain and chassis development.

Comprehensive Real-World Emissions Measurement

The OBS-ONE GS Unit combines the measurements required to calculate and evaluate gaseous mass emissions during on-road vehicle testing.

Measures CO, CO₂ and NOx
Supports NO₂ evaluation in selected configurations
Includes THC measurement in heavy-duty configurations
Measures or acquires exhaust-flow data
Records GPS position and vehicle speed
Monitors atmospheric temperature, humidity and pressure
Acquires exhaust temperature and pressure
Calculates mass emissions using synchronized measurement data
