Laser Particle Counter Identifies Particle Quantity and Size from 0.5 to 100 μm dia. Operates with both In-situ and Liquids.

Utilizing the principle of “near angle light scatter,” a revolving laser beam passes through the walls of a glass container or a flow-thru cell. When it is directed through a central “sensitive zone” the PC-2200 not only counts the particles in suspension, but tabulates their size as well. The analog signals generated by the light pulses are routed to a computer and digitized.

Spectrex provides three sealed calibration standards with each unit. Each standard contains a precise number of NIST traceable polystyrene spheres of known size in suspension and are sealed with inert Argon gas These standards have a proven stability of more than 2 years and provide efficient calibration within 10 minutes.
