Abstract
A particle counter and classification system including an imaging subsystem configured to determine the size and morphology of particles above a predetermined size in a fluid in a sample cell. A first stage magnetometer sensor subsystem is tuned to detect and determine the size of ferrous and/or conducting particles. An optional second stage magnetometer sensor subsystem is tuned to detect the overall ferrous particle content of the fluid. A processor subsystem is configured to calculate and report the number of particles in the fluid in a plurality of size ranges, their morphology, their classification as a particular particle type according to their characteristic morphology, the number of ferrous and/or conducting particles, and the overall ferrous content of the fluid.
