Laser diffraction particle size analyzer Winner2308A

static light scatteringfor the cosmetics industryfor the food industry

Product Overview
The Winner2308A is an intelligent, fully automatic laser particle size analyzer for integrated wet and dry measurement using laser diffraction theory (Mie and Fraunhofer). Wet measurement range: 0.01–2000 μm; Dry: 0.1–2000 μm. The system uses dual-beam, dual-spectrum detection and side light-scatter testing to provide reliable, repeatable particle size distributions for industrial quality control, research laboratories, R&D centers and testing institutions.
