Bettersizer 2600

Smart and robust
 laser particle size analyzer (wet and dry dispersion)

The smart and robust particle size analyzer, Bettersizer 2600, can deliver reliable particle size measurement results from submicron to millimeter. Both wet and dry dispersions are optional for Bettersizer 2600. Driven by the innovative optical system and Standard Operation Procedure (SOP), the 2600 strikes a harmonious balance between high-functionality, easy operation, low maintenance, and cost- effectiveness.
