YX-9300ST laser particle size analyzer

YX-9300ST laser particle size analyzer for non-metallic powder has many automatic features including automatic testing, automatic optical calibration, automatic sample feeding, automatic water supply and drainage, automatically eliminating air bubble, automatic cleaning and so on. Summed up in one sentence, that is, as long as the sample added to the circle pool, you can get accurate test results. Moreover, its software system is more powerful and flexible, and makes this laser particle size analyzer highly automatic, much more convenient to use and performance better. It adopts imported semiconductor lasers of power, long life and good monochrome; using specially designed large-size high-sensitivity photodetector array by large-scale integrated circuit manufacturing process; sample feeding using centrifugal pumps and micro-sample pool. It adopts Milosevic Theory and the free distribution model as the data-processing methods. High-precision data transmission and processing circuitry and a series of advanced technologies and manufacturing processes are adopted to ensure the equipment accurate and reliable, high test speed, good repeatability, easy operation and so on. The set of particle size analyzer integrates laser technology, computer technology and photonics technology, is particularly suitable to be used by colleges and universities, research institutes and laboratory of large enterprise.
