OCCHIO ZEPHYR ESR2 HEAVY DUTY PARTICLE CHARACTERIZATION SYSTEM
MEDIUM TO LARGE SAMPLES FOR GRANULAR AND BULK MATERIALS (LIQUID ACCESSORY OPTION AVAILABLE)
Occhio particle size and shape analyzers, are the collaboration of many years of focused research in the fields of optics, lighting, and digital imaging.
Common methods of particle size distribution analysis include laser diffraction, and sieve analysis, both of which are based on the assumption that the sample is comprised of spherical particles.
While these methods of gathering size distribution information generally provide usable results, they lack in accuracy, and application when compared with digital imaging technology, especially when particles are not round.
Fig 1.1 A monochromatic, collimated back-light acts like a caliper.
BY USING A PARAMETER CALLED MAXIMUM INSCRIBED DISC, NEAR PERFECT SIEVE CORRELATION IS NOW POSSIBLE, SINCE THIS EFFECTIVELY MEASURES THE WIDEST PART OF A PARTICLE, WHICH CONSEQUENTLY DETERMINES THE SIEVE APERTURE SIZE THE PARTICLE WOULD OR WOULD NOT FALL THROUGH. BECAUSE WE CANNOT TELL WHETHER A PARTICLE FALLS THROUGH A SIEVE APERTURE SQUARELY OR ON ITS' DIAGONAL, THERE WILL BE SOME VARIANCE.
ANALYZING THE PERFORMANCE ATTRIBUTES OF ABRASIVES, AND EXAMINING LENGTH AND WIDTH OF FIBERS, OR STRINGY PRODUCTS LIKE TOBACCO, AND SHREDDED CHEESE
PRIOR TO DIGITAL IMAGING THERE WAS NO GOOD WAY TO PERFORM QUALITY CONTROL TESTS ON LONG, STRINGY PARTICLES. SIEVE ANALYSIS IS ESSENTIALLY USELESS IN DETERMINING THE SIZE OF THESE CURVEY RUBBER SHREDS. OCCHIO IS ABLE TO EVEN MEASURE LENGTH OF CURVED PARTICLES.

OCCHIO DIGITAL IMAGE ANALYZERS HAVE THE ABILITY TO DETECT AND QUANTIFY BOTH PARTICLE SIZE AND PARTICLE SHAPE, PAVING THE WAY FOR THE ADVANCED ANALYSIS OF PARTICLES IN BOTH LIQUID AND SOLID FORMS.
CORRELATIONS TO OTHER PARTICLE SIZE ANALYSIS METHODS, LIKE SIEVE ANALYSIS AND LASER DIFFRACTION, ARE SEAMLESSLY EMPLOYED. EVEN SHAPE PARAMETERS LIKE LENGTH, FLATNESS, AND ANGULARITY IN AGGREGATES, OR THE LENGTH OF STRINGY PARTICLES LIKE SHREDDED CHEESE, OR TOBACCO, ARE POSSIBLE.
ONCE A BASIC CORRELATION HAS BEEN ESTABLISHED, THE RESULTS ARE FINE TUNED WITH THE OCCHIO CORRELATION PROGRAM, ALLOWING FOR TURNKEY SOLUTIONS TO PARTICLE CHARACTERIZATION.
