            Changes in particle size distributions and particle diameters are measured continuously, at intervals as short as 1 second, and the results
            are saved. Furthermore, the results can be subjected to multifaceted analysis and evaluation using functions such as 3D graphing. For

 Measurement Assistant Functions: allow preparing SOPs to ensure measurements are always performed using the same
 conditions and procedures.
 Creating, saving, and sharing measurement conditions and
 procedures, including pretreatment methods and conditions,
 ensures measurements are performed using the same conditions   Normalized Particle Amount (Diff)
 and procedures, even if performed by a different operator or at a
 different location or plant, and allows safely comparing data.
 Furthermore, when the measurement assistant function is used,
 measurement instructions for the operator are displayed on the   Particle Diameter (µm)
 screen. This enables even inexperienced operators to perform
 measurements correctly. In addition, administrators and operators
 can be assigned different operating privileges to ensure security.
