Abstract

In a particle measuring apparatus for measuring characteristics of particles by detecting light scattered at the particles while irradiating the particles in fluid with light, the scattered light is detected by means of a plurality of detectors and the characteristics of particles are determined by using pulse signals of detection signals coming from the plurality of detectors, which are coincident with each other.
