BT-9300S Laser Particle Size Analyzer is a BT-9300H upgrade products, it has the BT-9300H except all of the features, but also has an automatic adjustment of optical focal length, automatic, automatic drainage, ultrasound time, traffic and other special adjustable function. In addition, its software systems more powerful, more flexible, is a higher degree of automation, more convenient, better performance of the size distribution. It uses imported semiconductor lasers, high power, long life and good color; using a specially designed large scale integrated circuit manufacturing process by the large-size high-sensitivity photodetector array; by centrifugal circulating pump and the small sample cell into two kind of way; using full Mie theory and a variety of distribution models of data processing; using high-precision data transmission and processing circuit and a series of advanced technology and manufacturing processes, so that the instrument is accurate and reliable, test speed, repeatability and easy to operate, and other prominent features, is a laser technology, computer technology, a new generation of optoelectronic technology in one of the particle size measurement equipment. Particularly suitable for universities, research institutes, laboratories of large enterprises use.
