• 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
  • Manual air permeability tester according to Blaine for the determination of the specific surface (grinding fineness / Blaine value) of cement and other powdered materials in accordance with EN 196 and ASTM C 204.

      Design Lacquered steel sheet stand with mounted U-tube manometer. The manometer is equipped with a conical seat for the measuring cell and level marks for the manometer fluid. The measuring cell is made of stainless steel and fits exactly to the conical seat of the U-tube manometer. Behind the manometer a mirror is mounted to avoid reading errors. To record the ambient temperature a thermometer is installed on the instrument.
