Product overview
Winner2309C WinModule-301 is an intelligent, fully automatic dry-dispersion laser particle size analyzer based on Mie and Fraunhofer scattering principles. It integrates a high-sensitivity photoelectric probe system and a precision Canon lens optical path to deliver accurate, repeatable particle size distributions for laboratory R&D, quality control and research institutes.

Measurement range & key uses
Measurement range: 0.1–2000 μm. Designed for powder characterization in cement, ceramics, pharmaceuticals, dyes, chemicals, catalysts, metal and non-metal powders, calcium carbonate, kaolin, coffee, additive manufacturing powders and similar materials.

Advantages

• Automatic optical path alignment with four-phase hybrid stepper motors for micron-level positioning and stable measurement conditions.
• Professional pneumatic dry dispersion system providing efficient deagglomeration, stable airflow and uniform sample delivery — suitable for metal powders, new energy materials, ceramics, cement and AM powders.
• Modular automatic sample introduction reduces circulation length, prevents large-particle settling, lowers maintenance and simplifies cleaning.
• Advanced software with unconstrained free-fitting algorithms for multi-modal particle distributions and high resolution below 2 μm.
• Patented inverse Fourier (folded optical path) design with a wide detection angle (0.015–145°) for extended range and improved resolution; sealed optical path for dust protection.

Software & output
Supports multiple analysis modes (free distribution, R-R, log-normal, statistical models). Provides intelligent statistical comparison, customizable outputs (any D1–D100, cumulative percentages above/below sizes or within ranges), and exports interval and cumulative distributions, typical particle size values, graphs and reports. Reports exportable to Word, Excel, BMP, TXT and PDF. One-click automated sequence handles dust collection, air supply, feeding, measurement and data processing.

Applications
Applicable to cement, ceramics, pharmaceuticals, dyes, chemicals, catalysts, additives, pesticides, explosives, graphite, photosensitive materials, fuels, metal and non-metal powders, calcium carbonate, kaolin, coffee and other powders. Especially suitable where liquid dispersion causes reactions, shape change or loss (e.g., magnetic materials, herbal extracts, widely distributed powders).
