Particle Testing Authority (PTA), a division of Micromeritics Instrument Corp., has acquired a Freeman Technology’s FT4 Powder Rheometer to assist contract testing customers with concerns about powder flow and powder processing. The device uses bulk dynamic flow, shear, and process methodologies to quantify powder properties and determine flowability, aeration, permeability, compressibility, shear strength, and wall friction. PTA, Norcross, GA, provides material characterization services for fine powders and bulk solid materials.
