Abstract
The introduction of particle number (PN) emission limits in periodical technical inspection for passenger cars leads to the need of PN measurements for any individual car. Besides the need for measurement devices, a fast and simple PN calibration method to allow for high-throughput calibration is key. In this work we present such a calibration method to evaluate the linearity and the plateau counting efficiency region of a PN counter is on-site.
