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. -
Application 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
