Hands-on field sampling tool.

• Method of measuring turbidity in a body of water
• Useful in environmental studies
• Easy to read

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 measure turbidity, a measure of water clarity, which is in turn related to the amount of sediments or pollutants in the water.
