100cm Transparent Turbidity Tube with Secchi Disk

This elegantly simple apparatus is used to determine the transparency of water in lakes, streams, oceans as well as other bodies of water. The turbidity tube is a clear tube with a small Secchi Disc of alternating black and white quadrants and provides a quick and easy way to probe turbidity, which is a measure of clarity of the water, which is in turn related to the amount of sediments or pollutants in the water
