Equipment for Deterining the Size and Counting Particles Contained in a Suspension

摘要

The invention discloses equipment for determining the size of and counting particles contained in a suspension, e.g., blood corpuscles, with a measurement orifice through which the suspension can flow, that has two electrodes that are made of an electrically conducting material and are mounted in the wall, connected separately to an electrical circuit and are in contact with the suspension flowing through, characterized by the fact that the measurement orifice is formed by two insulating bodies, each with a hole, and joined together in such a way that the two electrodes are arranged between them in the form of thin layers that extend as far as the measurement orifice but do not project into it.
