とする散乱光式濁度測定装置。 A flow cell with an opening at the top, a light transmitter that irradiates light from above onto the surface of the sample water flowing through the flow cell, and a light transmitter that receives the scattered light of the irradiated light above the liquid surface and calculates the amount of light received. In a scattered light type turbidity measurement device that has a light receiving device that converts into a corresponding electric signal and an indicator that displays a turbidity measurement value based on the obtained electric signal, the device is connected to the light receiving device and detects a sudden change in the electric signal. and a hold circuit that is connected between the light receiving device and the indicator and holds the electrical signal sent to the indicator at the same level for a certain period of time based on the detection signal from the differentiator circuit. Scattered light type turbidity measuring device.
