Powder Tester PT-X

Hosokawa Micron's Powder Characteristics Tester PT-X employs the methods developed by Ralph L. Carr (Carr Indices) to determine the flowability and floodability of dry powders. The model PT-X utilizes state of the art features to identify the specific characteristics of powdered samples for a wide range of application fields.

Powder Tester PT-X


The PT-X determines 11 dry powder characteristics:
  • Angle of Repose
  • Cohesion
  • Aerated Density
  • Uniformity
  • Dispersibility
  • Compressibility
  • Angle of Fall
  • Packed Density
  • Angle of Spatula
  • Angle of Difference
  • Particle Size

Since 1968, when the original Powder Tester was developed, more than 3500 units have been delivered to companies throughout the world. The testing standards used by the Powder Tester made it the choice in development of more than 3000 patents: 1800 within the last 10 years.

The latest completely updated model PT-X, has features that have been suggested by the many worldwide users of earlier models, making the PT-X the most technologically advanced instrument to measure powder flow characteristics.
