Use this clear, redesigned, 60-cm tube to accurately measure the turbidity of shallow or flowing bodies of water where a Secchi disk can’t be used.
A single operator controls the water-level discharge from the tube by gently pushing it against the ground to activate the stop plunger when the 45-mm Secchi-disk design is visible.
Notes:
