TS-1000A – Analogue Turbidity Sensor

Turbidity is an optical feature of a liquid and a measurement of its clarity, a turbidity sensor is used to measure clarity. Determining scattered light levels within a column of water indicates turbidity. It is an important measurement to take in assessing the quality of a body of water as both plant and animal growth depend on turbidity levels.
