Abstract
A method of measuring turbidity includes irradiating specimen water with a light beam, using photoelectric conversion means for subjecting to photoelectric conversion the light scattered by fine particles in the specimen water, inputting a pulse signal as an input signal,obtainable from the photoelectric conversion whenever the fine particle passes through the light beam so as to measure its peak value in a peak holding circuit,obtaining the number concentration of fine particles in the specimen water on the basis of particle diameter divisions according to the measured value, and multiplying the number concentration by an individual coefficient on the basis of the particle diameter divisions in order to obtain the turbidity of the specimen water.
