EXCELLENT ACCURACY

Accuracy Verification of Standards
Duke standard samples were measured separately by the Bettersizer ST, 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 for standards is within 1%.

OUTSTANDING REPEATABILITY
Exceptional repeatability provided by Bettersizer ST 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

Repeatability Tests
The outstanding repeatability of Bettersizer ST, demonstrated by the following two consecutive tests.

Legendary Ease-of-Use

The Bettersize software provides various functions that greatly reduce your workload.

Ⅰ . Intuitive Software

Ⅱ . Intelligent Data Evaluation for Quality Control

Ⅲ . Performance Validation

Ⅳ . System Inspection

Cost-Efficiency & Robustness

Outstanding Robustness
- Integrated casting of the bottom plate to protect the instrument
- Accurate measurements can be achieved even after a robustness test
- Long-life fiber semiconductor laser source
- Durable circulation tank with casted stainless steel
- Power-adjustable ultrasonic disperser with dry run protection

Compact Design
- Save valuable workspace for factories and laboratories with an internal wet dispersion system
- The DLOS ensures result accuracy and reliability, while avoiding folding optics that are susceptible to misalignment

Simple Maintenance
- Simple disassembly of sample cells allows a quick cleaning, which can be easily accessed without professional tools and excessive clean formulations
- Auto-cleaning function for the circulation tank eases the maintenance work greatly
- Auto-cleaning process can be easily customized in the software

Low Cost of Ownership
- Entry-level price for a laser particle size analyzer
- A measurement range that covers most applications can be achieved with DLOS without additional cost for a second laser source

Standard Operating Procedure (SOP)
SOP is an easy solution for standardized and automatic testing. It ensures the measurement results are operator- independent, objective and reliable.

INNOVATIVE DLOS TECHNOLOGY

The DLOS (Dual Lens Optical System) is a patented optical system designed by Bettersize Instruments. In DLOS, one single laser source and two large Fourier lenses are utilized, and the combination of wide-angle forward, lateral and backward photodetectors allows consistent and accurate results with a measurement range from 0.1 to 1000 μm.
