Technical problems have yet to be resolved, and the measurement of particle size is one of the most basic and important aspects. In many cases, the size of the particle size not only directly affects the performance and quality of the product, but also has a significant relationship with the optimization of the process, the reduction of energy consumption, and the reduction of environmental pollution. In recent years, various new particle materials closely related to high-tech, national defense industry, military science, etc., especially the advent and utilization of ultrafine nanoparticles, have put forward new and higher requirements for the measurement of particle size. Not only requires fast and automated data processing, but also requires reliable and richer data and more useful information to meet the needs of scientific research and industrial quality control applications. TS-W series laser particle size analyzer is the latest generation of laser particle size analyzer carefully developed to meet the above new requirements of users. The instrument integrates the application of advanced laser technology, semiconductor technology, optoelectronic technology, microelectronic technology and computer technology, and integrates light, machine, electricity, and computer. The outstanding advantages of particle size measurement technology based on light scattering theory are gradually Instead of some traditional conventional measurement methods, it will surely become a new generation of particle size measuring instruments. And it plays an increasingly important role in the analysis of particle size distribution in the field of scientific research and industrial quality control.
