The Standard Operating Procedure (SOP) and automated analysis procedures have been developed to help users save precious time for quality inspection. Users can skip complicated operations with Bettersizer ST: Just click “Start,” add the sampleand the Bettersizer ST will provide the particle size distribution analysis for users.

Measurement consistency allows us to verify the outcome of the process without worrying about measurement errors. The system performance and reliability are excellent in manufacturing process of CaCO3. Auto-cleaning between samples is also made easy by Bettersizer ST. It has a very simple and intuitive user interface. Tests can be conducted by multiple production personnel due to its ease of use.

Innovative DLOS Technology

The Dual Lens Optical Systems (DLOS) is a patented optical system designed by Bettersize Instruments. In DLOS, one single laser source and two large Fourier lenses are used, and the combination of wide-angle forward, lateral and backward photodetectors enables consistent and precise outcomes with a measurement ranging from 0.1 to 1000μm.

Features

High resolution and precision guaranteed by two big Fourier lenses

Compact design avoids the need to use folding optics

Measurement range can be expanded with 86 high-speed photodetectors

Continuous incident light with consistent wavelength offered by one single laser source

Advantages

Measurement range — 0.1 to 1000 μm

Avoid Misalignment — The advancedesign of DLOS eliminates folding optics that are vulnerable to misalignment

More reliable results — Only one laser source is used to offer a continuous scattering spectrum with consistent wavelength

Cost-efficient — Reliable outcomes without a second laser source results in cost-efficiency

Excellent Accuracy
