YX-2001 laser particle size analyzer is a unique laser particle size analysis tester for magnetic powders like ferrite powders, smco powders, alnico powders, smco powders etc. The analyzer adopts special sample preparation and test mode to make magnetic particles in separate, homogenous, scattered condition instead of the aggregation caused by magnetic force. It utilizes the property that the particles can cause laser diffraction. It adopts a series of advanced technology and technics such as imported semiconductor laser generator with high power, long service life and good monochromaticity; large-size high precision photoelectric receiver array made by ASIC technique, multi-channel data transforming circuit and USB data transmitting lead to fast and precise test, easy operation and high repeatability. YX-2001 ends the history that magnetic particle cannot be tested and is significant for the test and control of the magnetic products quality as well.
