The FT4 Powder Rheometer® from Freeman Technology is a universal powder tester. It uses unique dynamic methodology, a fully automated shear cell (ASTM D7891) and several bulk property tests, including density, compressibility and permeability to quantify powder properties in terms of flow and processability. FT4 Powder Rheometers are installed around the world in a diverse range of industries including chemical, pharmaceutical, toners, foods, powder coatings, metals, ceramics, cosmetics and many others. They deliver data that maximise process and product understanding, accelerating R&D and formulation towards successful commercialisation, and supporting the long term optimisation of powder processes.

The FT4 Powder Rheometer – a universal powder flow tester for measuring powder flow properties and powder behaviour.
The FT4 was designed with one purpose in mind – to characterise the rheology of powders, or powder flow properties. This remains a primary function today, but the instrument,
