Semi-Automatic Air Permeability Instrument Model BSA II


The air permeability tester ToniPERM is designed for the determination of the specif c surface of powders, especially suitable for the permanent control of manufacturing characteristics in the daily laboratory work according to EN 196 and ASTM C 204.


Key benefits for the user:

✓ 5.7“ color display with touch screen operation for intuitive and user-friendly operation
✓ integration of the environmental temperature into the calculation of the specif c surface
✓ density, initial weight and porosity selectable acc. to the specific samples
✓ calibration using reference materials feasible
✓ any number of K-factors can be stored
✓ runtime indication resolution: 0.1 sec
✓ calculation of the specif c surface based on any number of single measurements on one powder bed
✓ integrated data base for storage of up to 300 measuring results including all test parameters
✓ integrated data base for 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 the test parameters to a data carrier in CSV format
✓ connection to laboratory information and management systems via software ToniLINK CEB
✓ ability to subsequently change the correction factor (K-factor) for an extended result evaluation



Using the piston the powder will be compacted within the permeability cell to a def ned volume. After the selection of the test material from the material data base and the entry of the test-specific parameters, the test is carried out fully automatically. Via a U-tube manometer, which is equipped with light barriers, a negative pressure is generated by means of a solenoid valve and a diaphragm pump. This negative pressure is compensated by an amount of air flowing through the powder bed in the measuring cell. Then the ToniPERM automatically evaluates the test, displays the result and stores the result including the test parameters in the database
