1) Why Image Analysis Method?

• Easy
  Capture an image of particles, identify particles, then measure their size and shape. Every step of image analysis is easy and clear.

• Shape analysis
  Based on a direct view of particles, it is possible to analyze not only the size of particles, but also their shape. 

• Seeing is believing
  The image analysis method determines the size and shape of every individual particle and then sums it up to form a statistic. Details of particle size or shape distribution can be accurately provided.

2) Why Dynamic Image Analysis Method?

• Efficiency
  A continuous particle flow passing through the measurement zone helps achieve a higher efficiency of the measurement.

• Oversized particle sensitivity
  The dynamic image analysis method is sensitive to oversized particles; it is even possible to estimate the size of oversized particles.

• Reliable results
  The maximized number of measured particles ensures the statistical significance of measurement results.

3) BeVision D2 Hardware: Guaranteed Accuracy and Efficiency for You

To measure the size and shape of particles over a great variety of applications, the BeVision D2 has equipped with a comprehensive range of hardware. Corresponding to the sample material properties, selecting the best hardware can help measure the size and shape of particles with optimum accuracy and efficiency.
