About Particle Counter Calibration
The primary standard for particle counter calibration is ISO 21501-4. Calibration is carried out by comparing the size and number of particles of a polydisperse, mainly atmospheric, aerosol measured by the calibrated gauge with the size and number of particles measured by a counter designated as the standard.
ISO 21501 incorporates tests designed to reduce count variability between different instruments. Specifically, it specifies counting resolution and counting efficiency tests to be performed at routine calibration cycles, typically every six or twelve months.
