Optical particle size analyzer Winner319B

laser diffractionlaserfor research

Product Overview
Winner319B is a bench-top spray laser particle size analyzer designed for droplet and aerosol size measurement. It uses the Fraunhofer diffraction principle with a parallel light path and a high-performance semiconductor laser (λ=635 nm). The split-type instrument (separate transmit and receive units) supports non-contact spray testing with a measurement range of 1–1000 µm (extendable to 0.1 µm) and is suitable for R&D laboratories, quality-control institutes and industrial test environments.
