DescriptionRelated Products The PSA2000M is a laser particle size analyzer designed for abrasive industries. It combines the Mie light scattering principle, a patented technique of Fourier transformation of converging light and an unconstrained fitting program, to ensure the reliability and reproducibility of the measurement results. The results execute the standards of abrasive industry. Main Features: Principle: Particles of different sizes scatters the illuminating laser into different patterns. In this instrument He-Ne laser is used to illuminate and a photon detector array measures the scattered laser. Software automatically converts the patterns into size distributions.
