The macroscopic, physical properties of a powder pile are the basic characteristics of powder materials. Knowledge of these properties is therefore a crucial factor in powder production, processing and packaging, as well as in the transport, storage and application of these materials.
Alongside the large number of measuring instruments for characterizing the microscopic properties of powders such as particle size, particle shape or BET surface area, which can only be used to estimate the macroscopic, physical properties of powders, we offer the PowderPro A1 system for fully automatic and precise measurement.

The characterization of the particle size distribution in concentrated suspensions or emulsions commonly found in ceramics and construction industry as well as food and cosmetic applications requires a method to analyze samples in their original concentrations and on a macroscopic scale. This can be achieved by employing acoustic spectrometry, which determines particle sizes in proportion to their respective masses by measuring the damping of ultrasonic waves in concentrated dispersion with particle sizes on the nanometer to micrometer scale.
