Abstract
Particle measuring apparatus 1 comprising slide plate 3 set between tanks 2a and 2b and having through-holes 8 to 11 passing through slide plate 3 and a pair of electrodes 4a and 4b, wherein through-holes 8 to 11 on slide plate 3 are formed by a group of through-holes with different diameters. When one of the through-holes 8 to 11 is brought to a position corresponding to connective holes 2c and 2d by driving unit 7, particle distribution is measured and analyzed in accordance with the electrical impedance when a sample suspension passes through the through-hole.
