・ When the cyclone type is used, the sample loaded in the special sample holder is sucked in while being rotated, then injected from the nozzle and measured. Particle Diameter (µm)
In addition, since a sample holder is used, there is no scattering of the sample nor do the operator's hands become soiled.

・ When compressed air, including the sample, flows through the injection nozzle, the shape,
area, and direction of the cross section is changed in order to obtain the large changes in
volume, pressure and direction of air flow. Therefore, agglomerates can be strongly
dispersed into air.
・ In order to obtain the optimum dispersion based on the properties of the sample one of
Standard dispersion nozzle (Type 1) Sample four differently shaped nozzles can be selected.
