Air Permeability Tester ToniPERM II

Air permeability tester for the automatic determination of the specific surface (grinding fineness / Blaine value) of powdered materials, especially for the permanent control of manufacturing characteristics in the daily laboratory work.


Key benefits for the user:

  • 5.7" color display with touchscreen operation for intuitive and user-friendly operation
  • alternating operation with two measuring cells enables a higher test frequency  
  • implication of the environmental temperature into the calculation of the specific surface
  • height adjustable optical sensors for the adaption of the cycle time to different types of material
  • calibration using reference materials feasible by the user
  • density, initial weight and porosity are freely selectable
  • integrated compartment for the storage of consumables and reference materials
  • any number of correction factors (K-factors) storable
  • runtime indication resolution: 0.1 seconds
  • calculation of the specific surface based on any number of single measurements on one powder bed
  • integrated data base for the storage of up to 300 test results including all test parameters
  • integrated data base for the storage of materials with different density and porosity
  • possibility to connect a printer for automatic raw data print out
  • USB interface for easy and fast export of test results including all test parameters
  • possibility to connect a dial gauge for the automated compensation of compaction deviations
  • improved comparability of the test results by separately calibratable measuring cells (compensation of minimum volume differences of the measuring cells)
  • ability to change the correction factor subsequently for an extended result evaluation
