Abstract
A uniformity output device for outputting a uniformity of particles in a slurry, in which an insoluble solid matter is mixed in liquid, includes: a pair of electrodes configured to apply AC voltage to the slurry; a measurement unit configured to measure impedance of the slurry on the basis of the response current flowing through the slurry when AC voltage with changing frequency is applied to the slurry; and a processing unit configured to determine the uniformity by executing a particle equivalent circuit analysis with a parallel circuit formed of a resistor and a capacitor as an element on the basis of the impedance measured by the measurement unit in accordance with the frequency.
