Transparency Tube

Ideal for measuring turbidity in streams where a Secchi disk can't be used.

• Clear polycarbonate

• Centimeter scale
• Seechi disk design 2" in diameter located at the bottom
• Drain hose with an attached finger crimp
• Aligned to GLOBE protocol

Students will measure water clarity and estimate stream quality by observing how much light passes through. This is a great tool for water quality testing and environmental science education. Simply fill the tube with water and look down to assess turbidity. The Secchi disk is screwed to a rubber stopper that can be removed for cleaning.
