Instrument Description: It can measure both the sample to be dispersed in the liquid and the powder material which cannot be dispersed in the liquid and must be dispersed in the gas.

working principle:
Using the scattering phenomenon of particles by light, the particle size distribution of the measured particles is estimated based on the distribution of scattered light energy. Through the integration and optimization of optical, mechanical, electronic, computer and other systems, Omega has made the Omega laser particle size analyzer have the advantages of good repeatability, wide dynamic measurement range and simple and convenient operation.
