PURPOSE:To provide a measuring cell, for a turbidity sensor, which can detect a precise turbidity by means of only one watertight container and one set of a light projector and a light receiver. CONSTITUTION:In a measuring cell for a turbidity sensor, a light projector 2A and a light receiver 2B are arranged and installed so as to be faced with each other at both ends of a slender watertight container 1, and a water injection port 3 and a water discharge port 4 are installed near both ends. Second water injection ports 6A, 6B are installed so as to be adjacent to transparent bodies 5A, 5B arranged on the front of the light projector 2A and of the light receiver 2B, a pipe 7 which supplies sample water to the main water injection port 3 is the branched, and a branch pipe 8 is connected to the second water injection ports 6A, 6B via a filter 9. |
