The FT4 Powder Rheometer®– a universal powder tester for measuring powder flow properties and powder behavior.

The FT4 was designed with one purpose in mind – to characterize 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 flow tester.

The FT4 employs unique technology for measuring the resistance of the powder to flow, whilst the powder is in motion. A precision ‘blade’ is rotated and moved downwards through the powder to establish a precise flow pattern. This causes many thousands of particles to interact, or flow relative to one another, and the resistance experienced by the blade represents the difficulty of this relative particle movement, or the bulk flow properties.

Excellent reproducibility is achieved by moving the blade in a precise and reliable way. The advanced control systems of the FT4 accurately set the rotational and vertical speeds of the blade, which defines the Helix Angle and Tip Speed.

Four testing methodologies in one instrument:

  • Unique Dynamic Flow
  • Fully Automated Shear Cell (in accordance with ASTM Standard D7891)
  • Bulk Properties
  • Process Variables
