S3500 – Particle Size Analyzer

The industry preferred laser diffraction analyzer ideal for particle characterization.

Microtrac S3500 Laser Diffraction Instrument
The Microtrac S3500 is the first particle size analyzer that uses three precisely placed red laser diodes to accurately characterize particles like never before. The patented Tri-Laser System provides accurate, reliable and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles.  The S3500 measures particle size from 0.02 to 2800 microns.
