About the FT4 Powder Rheometer

Powder Testing with the FT4 Powder Rheometer

The FT4 Powder Rheometer® was designed with one purpose in mind - to characterise the rheology, or flow properties, of powders. This remains a primary function today, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder tester.

In addition to the patented dynamic methodology, where a powder’s resistance to flow is measured whilst the powder is in motion, the FT4 also includes a shear cell for measuring the powder’s shear strength, a wall friction kit to quantify how a powder shears with respect to the surfaces of process equipment (in accordance with ASTM Standard D7891), as well as accessories for measuring bulk properties, such as density, compressibility and permeability. This range of measurement capabilities makes the FT4 a truly universal powder tester and the world’s most versatile instrument for measuring and understanding powder behaviour.
