Product OverviewWinner802 uses dynamic light scattering (DLS) with a digital correlator to derive the diffusion coefficient from scattered light fluctuations and calculate particle size distribution via the Stokes–Einstein equation. Intended for research laboratories, R&D centres and quality-control labs, the instrument supports coloured samples and provides reproducible particle size distribution outputs.
Key Features- Photon-correlation DLS principle for particle sizing based on Brownian motion.
- CR256 digital correlator with correlator resolution up to 8 ns and data throughput up to 162M.
- HAMAMATSU photomultiplier detector for improved sensitivity and signal-to-noise ratio.
- Optical-fibre path design for stability and reduced interference.
- Semiconductor temperature control, range 5–90 °C, accuracy ±0.1 °C.
- Automated operation: SOP presets, one-click testing; bilingual interface (Chinese/English).
