Method and apparatus for measuring turbidity

A method of measuring turbidity, comprising the steps of:

• irradiating specimen water with a light beam;
• subjecting to photoelectric conversion the light transmitted through the specimen water by using photoelectric conversion means;
• obtaining the number concentration of fine particles in the specimen water on the basis of particle diameter divisions according to a pulse signal obtainable from the photoelectric conversion each time individual fine particles pass through the light beam;
• 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.

A method of measuring turbidity, comprising:
