Laser Diffraction and Automated Imaging Particle Size Analyzer

Laser Diffraction & Microscope Imaging Combination

Stock Status: In Stock


Seamlessly combined laser diffraction and automated imaging into one system, Bettersizer S3 Plus can not only achieve a wide test range from 0.01 to 3500μm, but also provide reliable particle size distribution and particle shape information simultaneously. The combination of our innovative Dual lenses & oblique incidence optical system (DLOIS), auto refractive index measurement, and smart operation functions provide the most accurate, high-resolution, high sensitivity, excellence repeatability, cost-effective, and easy-to-use Bettersizer S3 Plus you can ever imagine possible.


  • Measuring range: 
  1. Particle size from 0.01μm to 3500μm 
  2. Particle shape from 4μm to 3500μm 

  •  Unique Dual Lens & 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. 
  •   Automated Imaging analysis to provide particle shape information, especially useful for coarse particles; plus the ability to correlate particle size and shape analysis. 
  •  Auto refractive index measurement: ability to pre-determine the optical parameters of materials that will closer match the true value of the sample, enhancing the accuracy of the measurements of materials with unknown refractive index. 
  •  Fully automatic operation minimizes workload as well as operation error. 
  •  Measuring results of size and shape display in real time, rapidly track result changes with user-defined parameters.
