Turbidity can be measured directly with a turbidity meter or turbidity sensor (submersible turbidimeters), or indirectly with a secchi disc/tube.

Turbidity is one of the more difficult considerations to measure. How murky or opaque water is can be a subjective measurement. There are currently three methods for measuring turbidity, and two for measuring total suspended solids. These methods have expanded the range and accuracy of turbidity measurements from basic object visibility tests and historical visual extinction methods.

Turbidity can be measured with a turbidimeter or turbidity sensor. Turbidity sensors may also be referred to as submersible turbidimeters.

Water clarity methods involve a secchi disc or tube. Turbidity meters use nephelometry (90-degree scattering) or other optical scatter-detection techniques for fast, accurate turbidity measurements on water samples. Turbidity sensors also use optical technology, but instead of using sample cells, they can be placed directly in the water source to measure turbidity. In addition, turbidity sensors can be used for continuous turbidity measurements. However, when using these sensors, consistency is key.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][/vc_column][/vc_row]
