PROBLEM TO BE SOLVED: To provide a turbidimeter constituted so as to keep equal turbidity by preventing the precipitation of the turbidity component in a measuring cell even if the flow rate of water to be measured is reduced to realize a stable measured value. SOLUTION: In the turbidimeter constituted so that a cylindrical measuring cell, which has an injection port for injecting water to be measured and a discharge port for draining the water to be measured, filled with a predetermined volume of the water to be measured is irradiated with measuring light from the light source provided to the first end surface of the measuring cell and the turbidity of the water to be measured is measured on the basis of the transmissivity of the measuring light detected by the photodetector of the second end surface of the measuring cell, a revolving flow is formed in the measuring cell by the injection pressure of the water to be measured in the injection port.
