ABSTRACT:
Apparatus for obtaining automatically the distribution of volume or mass of particles suspended in a sample. The sample is analyzed in successive sequences or sections each representing a magnitude of given particles. A counter is provided for counting the particles in the sections, and a measuring circuit determines a value which is proportional to the time required by the counter to obtain the number of counted particles. The values are transmitted by a differential circuit to a display device which records directly, such as in a graph, the distribution of the particles in the sample.
