Bettersize2000S spray laser particle size analyzer Introduction
Bettersize2000S Fog Drop Laser Particle Size Analyzer is a laser particle size analyzer developed by Dandong Baxter for testing the size distribution of fog droplets. The system consists of a host computer, an optical axis reference frame, a lifting bracket, a nozzle adjustment system, a droplet generation system and software. Its role is to optimize the nozzle design, determine the spray pressure, and evaluate the spray effect by measuring the droplet size.
Unlike conventional laser particle size analyzers, which perform particle size testing with a small sample thickness (less than 5mm behind the sample cell), the droplet laser particle size analyzer has a wider sample thickness (usually 100-1000mm). In order to adapt to this special situation, Bettersize2000S uses the Fourier optical system recommended by international standards. A parallel laser beam is irradiated to the spray droplet area. The large-diameter Fourier lens is used to receive the scattered light signal generated by the droplet, and The Mie scattering theory was used to perform the inversion calculation to obtain the particle size distribution of the droplets. The nozzle adjustment system and the droplet generation system can analyze the droplet size at different heights, positions and pressures in the spray field, and provide reliable particle size data for optimizing nozzles, optimizing spray conditions, and studying the droplet diffusion law.
Bettersize2000S spray laser particle size analyzer has outstanding dynamic characteristics such as wide dynamic range, good accuracy and repeatability, easy operation, and wide adaptability. It also has an automatic adjustment system for centering and measuring area, which is suitable for pesticide, plant protection, and pharmaceutical spray evaluation. , Various nozzle research and other fields. In the field of pharmaceutical sprays, pesticide sprays, and various engine combustion efficiency studies, reliable test data can be provided, and its accuracy and repeatability indicators fully meet international standards.
