The method applied determines the fineness of cement or other products by measuring the elapsed time for a given quantity of air to pass through a compacted bed of cement. Advantages: simplicity/ user friendliness; no calculation needed, no use of monograph, the machine do it for him; several using mode, simple, double and quadruple test; and possible to work with variable porosity in an easy way;special diagnostic mode; and automatic calculation of the K for the calibration.
