EXCELLENT ACCURACY

Accuracy Verification of Standards
Duke standard samples were measured separately by the Bettersizer ST laser particle sizer, showing the distribution peak in the correct position and narrow distribution with high accuracy.

The red line is the nominal size range of standards ± 1.0%, and the black dots are the measured sizes. As shown in the figure, the measurement accuracy of Bettersizer ST laser particle sizer for standards is within 1%.

OUTSTANDING REPEATABILITY
Exceptional repeatability provided by Bettersizer ST laser particle sizer ensures the reliability of the results. Rapid measurements with consistent and reliable results can ease your workload on quality control. 

Excellent Repeatability From: - Stability of signal transmission systems - Efficient dispersion system - Automatic alignment keeps the instrument always in optimum condition - Signal acquiring rate up to 3500 times/second
