Description
The Freeman FT4 was designed with one purpose in mind: to characterize the rheology of powders, or powder flow properties. This is still the primary function, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder flow tester.
The FT4 powder tester is unique in many ways. Below are some critical features for assessing industrial value:
- The ability to simulate powder processing conditions, by testing samples in a consolidated, moderately stressed, aerated or fluidized state
-
The application of multi-faceted powder characterization to assess dynamic powder flow, bulk, and shear properties to construct the most comprehensive understanding of how a powder behaves
-
Unparalleled sensitivity, enabling the differentiation of powders that other testers classify as identical
Freeman Technology, developers of the industry-leading FT4 powder rheometer, became part of the Micromeritics family in 2018. In 2025, Micromeritics and Freeman joined Malvern Panalytical, bringing powder flow expertise into the wider materials characterization portfolio.
