Description
Features and Benefits
•Measuring range:
Particle size from 0.1μm to 1000μm.
• Dual Lenses Optical System (DLOS): optical design provides accurate results for particle size analysis.
• Standard Operation Procedure (SOP): offers a one-button operation.
• Compact design: saves work space.
• Automatic alignment and automatic testing lead to good repeatability with relative standard deviation (%RSD) of less than 1%.
