DLS-802 nano particle Size Analyzer,Gold APP Instruments_specification/price/image

Product Detail
Company Profile

DLS-802 dynamic light scattering nanometer particle size analyzer which based on the dynamic light scattering principle, the first manufacturer which use digital correlator in China. It was upgraded from DLS-801 which is the first set of nanometer particle size analyzer in China. Based on Brownian motion principle, smaller particle, faster speed, bigger particle, more slowly. It adopts 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 angles, and calculate particle diameter and distribution according to stokes-Einstein equation. the machine is with characters of fast calculation, high resolution ration, good accuracy, and repeatability, therefore it’s widely used in company product lab research and university.
