Description

PSA-N802 dynamic light scattering nanometer particle size analyzer, based on the dynamic light scattering principle, is the first one to use digital correlator in China. And It’s upgrade from Winner801, which is 1st set of Nanometer particle size analyzer. Based on Brownian motion principle, smaller particle, faster speed, bigger particle, more slowly. It adopt great performance of Japan HAMAMATSU photomultiplier and self-developed high speed digital correlator as core parts, get diffusion coefficient by test scattering light change in some angle, and calculate particle diameter and distribution according to stokes-Einstein equation. The machine is characterized by fast calculation, high resolution ration, good accuracy and repeatability, therefore it’s widely used in company product lab research and university use.
