Overview
Winner2309B WinModule-201 is an intelligent, fully automatic wet-dispersion laser particle size analyzer based on Mie and Fraunhofer scattering principles. It integrates a high-sensitivity photoelectric detection system with an imported Canon lens optical path to ensure measurement accuracy and repeatability. The instrument is designed for research institutes, university laboratories, R&D centers and quality control laboratories in industrial applications.

Advantages

• Automatic optical-path alignment using precise hybrid stepper motors for micron-level positioning and stable measurements.
• High-stability circulating dispersion reduces sedimentation and agglomeration; coordinated ultrasound and circulation control for flexible dispersion intensity.
• Modular wet/dry design with shortened circulation path to limit large-particle precipitation and reduce maintenance.
• Software supports unconstrained free-fitting for multimodal particle group analysis and provides high resolution below 2 μm.
• Patented reverse Fourier (folded) optical-path design extends test angle range and improves measurement range and resolution; sealed optical path for dust protection.
