OBS-ONE PN Unit
On-board Emissions Measurement System
On-board PN measurement for real-world results
The OBS-ONE PN unit is an on-board emissions measurement system for analyzing the solid particle number concentration within the specified particle size range under real-world driving conditions. The unit uses a condensation particle counter which is recommended principle by the Particle Measurement Programme (PMP), one of working groups affiliated with UNECE.
The PN unit combines with the GAS 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).
