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.
