Abstract
A particle size distribution analyzer comprising a particle detector adapted to produce signals in response to the sizes of particles by electrical or optical differences between a liquid and the particles dispersed therein, a plurality of comparators connected in parallel to said particle detector for producing pulses in correspondence with said signals, counters connected to each of said comparators for counting said pulses, a data input/output unit connected to each individual counter, whereby said input/output circuit receives signals sent in parallel from said counters, a keyboard unit connected to said input/output circuit operative to enable various conditions to be input from the outside, a central processing unit circuit, a read only memory and, a random access memory connected to said later input/output unit for statistically processing the pulse received, and a data output unit connected to said data input/output unit, said data output unit including at least a recorder.
