HORIBA's CAMSIZER P4 Digital Image Processing Particle Size and Shape Analysis System provides rapid and precise particle size and particle shape distributions for dry powders and bulk material in the size range from 20 microns to 30 millimeters. This technique provides a wide variety of information about the sample, from a general size measurement, to shape parameters that can be closely correlated to specific performance characteristics. This also allows correlation to existing data from techniques as diverse as sieving, microscopy, and hand caliper measurement.

The CAMSIZER P4 integrates higher resolution cameras and a faster interface between the cameras and the PC than the previous generation, which allows for a new internal data structure that stores large amounts of image data to a particle library. Images and contours of particles with defined properties can be extracted from the particle library and displayed or processed off-line. Similar image libraries are well known from conventional static microscopes. The CAMSIZER P4 particle library, however, handles millions of single particle images incredibly fast.


In addition to the well-known two-dimensional display of results, the CAMSIZER P4 features a new 3D Cloud (3 dimensional graph) which allows displaying 3 parameters (for example particle size, aspect ratio and transparency).


Faster cameras with higher resolution, a brighter light source and improved data processing capabilities differentiate the CAMSIZER P4 from its predecessors. These improvements increase the measurement speed (~ 1 - 3 minutes); allow more precise shape analysis of small particles and an extended size measurement range.

Key Features
