Overview

Features and Benefits

Measuring range:
Particle size from 0.01μm to 3500μm.
Particle shape from 100μm to 3500μm.

Dual Lenses & Oblique Incidence Optical System (DLOIS): eliminates the fitting error of double beam system, enlarges detection angle (0.02 to 165 degree) and assures high sensitivity, resolution and accuracy.

Particle size & shape: one CCD camera with 120 fps, 1.3 Mpixel and 0.5x lens. Combine particle size shape analysis.

Refractive index measurement: pre-determine the refractive index of materials; improve the accuracy of measurements of materials with unknown refractive index data.

Ease of use: Standard Operation Procedure (SOP), automatic alignment, automatic circulation & dispersion system, and the powerful software make sample analysis on Bettersizer S3 a one-button operation.

Intelligent Particle Sizing Performance

Bettersizer S3 represents the latest Bettersize particle size analysis technology for wet dispersion solution. Measuring range from 0.01µm to 3500µm can meet the most stringent requirement of different industries and a variety of test samples.

Accuracy
The accuracy of Bettersizer S3 as verified by measurements of eight standard samples.

Resolution
Detection limit test : A mixture reference standard samples of 3.1 µm and 5.1 µm nominal diameter was used to gauge the resolution of the Bettersizer S3 against the industry benchmark particle sizing instrument. The mixing ratio of 1.65 was used for the test. Bettersizer S3 clearly out-resolve the benchmark instrument as shown in the following graphs.

Sensitivity
Test methodology: Measurement with a mix reference standard sample of 0.3mm, 0.85mm, and 3.5mm was performed against a benchmark instrument. Bettersizer S3 resolves three peaks in the measurement result, while the benchmark instrument only able to resolve two peaks.
