Transparency / Turbidity Tube ( Code:TT ) Just as a Secchi disk is used as a measure of lake quality, a transparency tube can be used to estimate stream quality as it relates to solids in the water. Similar tools are called, Australian turbidity tube, or sediment stick. Citizen groups, schools and local governments can use transparency tube readings as a relative measure of stream quality. The 1 ¾ inch, clear polycarbonate tube is marked with an easy to read black numbers on a white tape in centimeters. Two lengths are available: 60 cm. and 120 cm. A drain tube with a crimp are supplied so the sample can be drained off until the "Secchi" pattern on the bottom just appears. The height of the water column is then recorded. Quantity discounts are available. Made with Secure StopperTM. Made in the USA. 60 cm Price: US $38.50.

Secchi-Tube (Code ST-60) or (ST-120) The Secchi-Tube is designed to function like the traditional Secchi disk that is used in lake monitoring. A weighted Secchi disk is lowered into the tube by a line, allowing the user to raise and lower the Secchi disk within the same water sample numerous times. This method allows for averaging the water transparency readings. At the top of the Secchi-Tube is a hole that drains excess water off to bring the water sample level down to the "zero" mark on the centimeter scale. The Secchi-Tube is made of polycarbonate with an easy-to-read centimeter tape. Features the Secure StopperTM and all stainless steel hardware. 60 cm Price: US $38.50. 120 cm Price: US $52.95.

What's the Difference Between the Turbidity and Secchi Tubes?
If your protocols requires multiple readings on the same sample the Secchi tube allows a person to do so without having to re-pour the sample into the tube. The Turbidity tube requires catching the sample in a bucket and then pouring the sample back into the tube. The Secchi-tube does not allow unsuspended material to settle on the disk as readily as the turbidity tube does with its stationary black and white disk.
120cm turbidity tube ( Code:TTH )
with a release mechanism operated by a handle is designed for a convenient one-person

of water can be precisely regulated via the extension handle while observing the
Secchi pattern and taking the reading. Price: US
