Measure water’s degree of visibility with this turbidity tube. Measures turbidity in streams where a secchi disk can’t be used. The rubber tubing is 23-1/2 (60 cm) in length and features a centimeter scale on one side and a secchi disc design, 1-3/4 (4.5 cm) in diameter, on the bottom. The secchi design is screwed to a rubber stopper that can be removed for cleaning. Drain the tube with the drain hose and attached finger crimp.
