Details

The Turbidity Tube with Secchi Disc is the perfect tool for measuring the water clarity of ponds, lakes, streams, oceans, and other sources. It consists of a shatter-resistant plastic tube fitted with a clamped drainage hose and a rubber stopper with a Secchi disc at the bottom. Easy to use and accurate, simply fill the tube with your sample and slowly drain it by loosening the Hoffman clip on the hose. Once the alternating black and white quadrant pattern of the Secchi disc becomes visible from the top, record the height of the water as measured by the 120cm scale printed on the outside of the tube. The size is 51 inches tall x 2 inches in diameter.
