Abstract
A device for use in determining the characteristics of particles dispersed in a medium is described. The device has a sample cell for holding a sample containing particles dispersed in a medium. A transducer is positioned to emit sound waves into the sample of the sample cell. A mirror surface is positioned for translational movement within the sample cell without changing the level of the sample in the cell, for movement without the use of dynamic o-ring seals, and is positioned to reflect sound waves emitted by the transducer.
