Turbidity Tube, 60cm length

This item is ideal for monitoring turbidity in relatively shallow lakes and streams where a secchi disk would be impractical.  Follow these simple steps to obtain your reading:

• Fill the 60cm tube and look down the column of water at the submerged disk.

• Loosen the clamp on the drain tube and release water until the black and white quadrants at the base can just be resolved.

• Use the scale to read the depth of water to the nearest centimeter.

• Average the results from several observers.

Constructed from tough clear plastic that is suitable for field use.
