Need to determine how clear the water is? Measure the water's degree of visibility with our turbidity tubes.
This tube measures turbidity in streams where a secchi disk can't be used. The clear polycarbonate tube is 60 or 120 cm in length and features a centimeter scale on one side and a secchi disk design, 4.5 cm in diameter, on the bottom. The secchi design is screwed to a rubber stopper that removes for cleaning. Drain the tube with the drain hose and attached finger crimp.
• In two lengths for different turbidity requirements
• Ideal for GLOBE program
• Economical
How to use:
1. Fill the tube with water sample and look down the tube.
2. Drain off water until the secchi disk design is visible.
3. Record the reading on the scale. |
