Transparency Turbidity Tube

The Transparency Turbidity Tube is used to estimate stream quality as it relates to suspended materials in water, measuring water clarity. Just as a secchi disk is used as a measure of lake quality, the transparency tube is an excellent reference for the study of water quality. The 1 3/4" diameter clear PVC tube is marked in cm from 0 to 60 with a 4.5 cm standard secchi disc pattern at the bottom of the tube. To use, the tube is filled with water and drained off using the drain tube until the secchi pattern appears. The height of the water column is then recorded. Each reading becomes a reference for measuring changes.
