Metrology & calibration


The calibration of instruments measuring suspended particle matter presents some difficult challenges. Unlike gas measurements, where traceable mixtures of calibration gases can be purchased, calibration of particle measurement instruments requires the generation of an aerosol in real-time, and its simultaneous measurement with the instrument to be calibrated, and a reference system.

Cambustion's CPMA Electrometer Reference Mass Standard allows a wide variety of mass concentration measuring aerosol instruments to be traceably calibrated.

Cambustion's Aerodynamic Aerosol Classifier is an ideal source of calibration particles for optical counting instruments as it can classify up to several microns in size.
