摘要： 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 7 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 13, 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.

摘要： A sample flow, including a plurality of components which have different types of spectra and are subjected to flocculation, is irradiated with a light of beam including two or more wavelengths. The transmitted light beam is received by a photoelectric converting device, and electric signals corresponding to respective wavelengths of the transmitted light beam are obtained. The correlation coefficient between the electric signal is calculated, from which the flocculation process of the sample flow with regard to the elapsed time can be easily and quickly detected.
