Laser diffraction particle size analyzer Winner3008A

laser light scatteringlaserfor research

Overview
Winner3008A is a laser particle size analyzer with a dry dispersion unit, offering both manual and fully automatic operation modes. Based on Mie scattering and a converging-light Fourier-transform optical path, it uses a high-performance laser and a sensitive ring photodetector array to deliver high repeatability and accuracy. The instrument disperses samples in compressed air using a patented turbulent dispersion method, precision feeder and powder-spray pump, with an oil-free silent gas source to ensure complete dispersion of dry powders, including materials sensitive to liquids.

Key Features

• Selectable full automatic or manual operation modes.
• Patented dry-turbulence dispersion ensuring thorough powder dispersion.
