Freeman Technology FT4 Powder Rheometer®


FT4 Powder Rheometer®

The FT4 Powder Rheometer is a universal powder tester - three instruments in one, combining the Freeman patented blade methodology for measuring flow energy with a range of shear cells, wall friction modules and other accessories for measuring bulk properties.       
The optimal approach for powder assessment is firstly to use testing methodologies that provide reproducible data and secondly to evaluate flow performance in ways that relate to powder behaviour in real industrial processes. This means quantifying the effects of consolidation, vibration, segregation, moisture uptake, fines, aeration, flow rate, air entrainment and a number of other factors. Such characterisation using complementary methodologies has wide application in the formulation, processing and QC sectors of most powder processing industries.


  • Three instruments in one – rheometer, shear cell and compression tester       
  • Powder conditioning that allows exceptional reproducibility of measurement       
  • Automated testing and analysis - independent of the operator       
  • Quick and straightforward operation- tests completed in minutes       
  • Ability to evaluate consolidated, conditioned and aerated / fluidised powders       
  • Unique measurement of aeratability of powders       
  • Small volume of sample - down to 1ml in the case of the miniature shear cell       
  • Three test vessel standards – 25, 50 and 62mm diameter for different sample volumes       
  • Family of three shear cells, 80, 10 and 1ml capacities       
  • High sensitivity dynamic mode for differentiating between very similar powders       
  • Can evaluate process variables such as attrition and segregation
