Bettersizer ST

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%.
