Haver CPA Particle Size and Shape Analyser

Photo-Optical particle size and shape analysis of fine material within the range of 34µm to 25mm.

W.S Tyler's CPA can not only measure the size of particles, but can also be used as a particle counter.

The CPA Particle Size Analyser user can select from a virutally infinite list of measurement 'opening' for custom analysis. The machine conveys dry, free flowing material samples to be examined by a camera lens taking approximately 20 000 scans per second. The results are recorded, stored and before being processed, reorganised and formatted by the Windows™ based software.

Real time counts of material may also be performed using the CPA, resulting in a distribution curve based on the actual number of particles measured within a given size range.

Collecting and examining samples in real time can provide valuable information before the material finds its way to final product.
