On-board Emissions Measurement System for NH3/N2O
OBS-ONE IRLAM Unit - HORIBA, Ltd.
The OBS-ONE IRLAM unit is an on-board emissions measurement system for analyzing the NH3/N2O under real-world driving conditions and supports our customer’s future regulatory development.
The IRLAM unit combines with the GAS unit and the PN unit to measure the specified exhaust gas components, along with the exhaust gas flow rate, the GPS position, and the atmospheric conditions (temperature, humidity, pressure).

On-Board Systems
OBS-ONE series
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.
