I. Product Introduction

        The Bettersize3000plus Laser Image Particle Size and Shape Analyzer is an intelligent laser particle size analyzer that uses a semiconductor-pumped 532 nm wavelength polarized laser as the light source. It adopts a single optical path system with full-angle measurement, ensuring no dead angles in scattered light detection, and offers top-level resolution, which is a patented technology of Bettersize Instruments. At the same time, it combines a dynamic particle image measurement system on the basis of laser diffraction measurement, which improves the measurement accuracy for coarse particles. Moreover, using Bettersize's proprietary technology, the laser diffraction data and image data can be fused to provide combined results, and the image method can also provide particle shape information. The combination of laser diffraction and image method is the first of its kind in China by Bettersize. Another notable feature of this instrument is its ability to measure refractive index, which is a very important parameter in laser particle size analysis. The correctness of this parameter is crucial to the accuracy of the measurement results. Therefore, Bettersize has developed an innovative refractive index measurement system based on the Bettersize3000plus instrument, combined with years of research results, ensuring the reliability and accuracy of the measurement results.

        The combination of laser diffraction and image method, as well as the refractive index measurement technology, are leading-edge technologies worldwide. Therefore, the performance of the Bettersize3000plus is world-class. It also has functions such as concentration measurement, specific surface area estimation, and specific gravity estimation. Other features include automatic measurement, automatic alignment, automatic water filling, automatic drainage, automatic bubble elimination, and automatic cleaning. It uses a high-performance imported semiconductor-pumped laser with a lifespan of more than 25,000 hours; and imported high-precision lens groups for clear imaging with minimal distortion, ensuring that weak scattered light signals at various angles are not missed. The imaging system uses a German high-speed CCD and a high-quality telecentric lens, ensuring clear particle imaging. With high-speed particle recognition software, it can analyze tens of thousands to hundreds of thousands of particles per minute. This instrument has outstanding features such as accuracy, reliability, good repeatability, simple operation, and fast measurement speed. It is a new generation of high-performance particle size analyzer integrating laser technology, computer technology, digital image technology, and optoelectronic technology. It is at the world's leading level and can compete with foreign particle size analyzers. It is especially suitable for laboratories in enterprises, universities, and research institutes.
