PARTICLE COUNTER

摘要

A vacuum pump and a pressure regulator are connected to a liquid trap for developing a predetermined vacuum within the trap. An electrode housing has a cavity formed therein, which is divided into first and second chambers by a partition having an aperture connecting said first and second chambers. An electrode is mounted in each of said first and second chambers. Said second chamber is in communication with the liquid trap and said first chamber has a tube extending downwardly into a sample of fluid having dispersed particles contained in a container so that the fluid sample is drawn from the container into said first chamber through the aperture to said second chamber and thereafter into the liquid trap.
