Bettersize3000plus laser image particle size 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 full-angle measurement optical path system. The scattered light detection angle has no dead angle and has the highest The resolution is patented by Baxter. At the same time, a dynamic particle image measurement system is combined on the basis of laser scattering measurement to make the measurement of coarse particles more accurate. At the same time, Baxter's proprietary technology can be used to fuse laser method data and image method data. The test results, and the image method can also give information on the grain shape. The combination of the laser method and the image method is the first initiative of Baxter in China. This instrument also has a remarkable feature that it can measure the refractive index. The refractive index is a very important parameter in the measurement of the laser particle size analyzer. Whether it is correct or not has a crucial effect on the accuracy of the measurement results. Then Baxter Based on the Bettersize 3000plus instrument, combined with many years of research results, we have developed a creative refractive index measurement system, so that the true and accurate measurement results of the instrument can be reliably guaranteed.
The combination of laser method and image method, refractive index measurement technology, these two technologies are also leading-edge technologies in the world, so the performance of Bettersize3000plus is the top in the world. It also has functions such as concentration measurement, specific surface area estimation, and specific gravity estimation. In other aspects, it has special functions such as automatic test, automatic centering, automatic water inlet, automatic drainage, automatic bubble elimination, and automatic cleaning. High-performance imported semiconductor pump laser with a lifetime of more than 25,000 hours; the use of imported high-precision lens groups, clear imaging, and small distortion, ensuring that weak scattered light signals at various angles are not leaked. The imaging system uses German high-speed CCD and high-quality telecentric lens to make the particles clear.
