About Turbidity Sensors
Turbidity sensors measure suspended solids in water, typically by measuring the amount of light transmitted through the water. They are used in river and stream gaging, wastewater and effluent measurement, control instrumentation for settling ponds, sediment transport research, and laboratory measurements.
