Hosokawa Micron Powder Characteristics Tester Model PT-S
The Powder Characteristics Tester, Model PT-S, is a single instrument which provides seven mechanical measurements and three supporting measurements of dry bulk powders. It complies with Standard Test Method ASTM D6393-99 "Bulk Solids Characterization by CARR Indices". It has been developed to improve handling, efficiency, and accuracy in testing the bulk properties of dry powders.
The primary functions of the PT-S device are to provide measurements in a single convenient unit, an additional basis of data for quality control of powdered products, and numerical evaluations of flowability and floodability of powders. The Powder Characteristics Tester package includes the powder tester unit and dispersibility tower (shown in picture), a Dell desktop computer with PT-S Software, compatible electronic balance, necessary tools and accessories including certified sieve screens, and dust containment system (if optional vacuum is purchased).
Bulk materials have inherent properties described by the particle size distribution, bulk density, particle shape, surface area, moisture content, cohesiveness, hygroscopicity, etc. Especially important is the flow behavior (flowability) and the flood behavior (floodability) of powders during production and in their respective application uses.
