opticallaserfor the food industry

Product overview
Winner2309A WinModule-301 is an automated dry-dispersion laser particle size analyzer based on Mie scattering and Fraunhofer diffraction. The instrument integrates a high-sensitivity photoelectric detector, a Canon lens optical path and a modular dry dispersion system to deliver repeatable particle size distributions for powders used in industry and research.
