This test method concerns the determination of the particle size of Portland cement, limes and similar powders using the Blaine air permeability apparatus. The measure of fineness is expressed in terms of the specific surface area (the total particle surface area) in square centimetres per gram or square meters per kilogram. This advanced apparatus fulfils both the EN 196-6 requirements and those concerning the validations demanded of the automatic methods by the ASTM C204. The accuracy and precision of results obtained using this apparatus exceed those acquired using the manual method. Calibration of the apparatus must be done using a cement surface standard reference such as the reference material. To obtain the most accurate results, the test should be performed in a temperature-controlled environment.

• The testing procedure is simple and quick.
• The calculation accuracy of the test results is high.
• 800*480mm colour touch screen display.
• The data export function is available.
• The test data is printed in real time, and the historical data is printed again.
