An apparatus for analyzing particles suspended in a fluid. The fluid has electrical properties different from that of the particles. The fluid and particles move from a first fluid containing portion to a second fluid containing portion through a conduit or aperture. A first pair of electrodes, each electrode of the pair being in a respective fluid containing portion. A constricted electrical path is defined between the first and second electrodes, and the path extends along t:he aperture. At least one other pair of electrodes is positioned in a non-encircling arrangement, and are aligned with each other and transversed to the constricted electrical path. This configuration eliminates many common errors suseptible to other devices.
