YSI Turbidity Standards
- Designed and manufactured to the highest quality standards
- Based on a suspended polymer bead
- Does not pose the health risk of traditional formazin solutions
|608000||6080 turbidity standard, 0 FNU (ProDSS & EXO); 0 NTU (6136), 1 gallon|
|607200||6072 turbidity standard, 12.4 FNU (ProDSS & EXO); 12.7 NTU (6136), 1 gallon|
|607300||6073G turbidity standard, 124 FNU (ProDSS & EXO); 126 NTU (6136), 1 gallon|
|607400||6074 turbidity standard, 1010 FNU (ProDSS & EXO); 1000 NTU (6136), 1 gallon|
YSI's polymer-based standards are prepared and labeled so they are traceable to the EPA's primary standard, Formazin. Solution calibrates instruments for maximum accuracy; is extremely accurate and stable.

Two autonomous underwater vehicles are drifting through Lake Ontario, monitoring a slew of environmental metrics, according to a release from New York Sea Grant. The high-tech equipment is recording data on fish productivity, food web changes and algae levels.
Each AUV weighs 42 pounds, is six and a half feet long and has a slew of sensors, including side scan sonar and 10-beam Doppler. Mapping capability complements collected parameters like temperature, turbidity, pH and levels of oxygen and phosphorus, among others.
The research is made possible through the Cooperative Science Monitoring Initiative between the US and Canada called for under the Clean Water Act of 1972.Read More
Wind probably isn’t the first thing that people think of when considering causes of poor water quality, but sediment disturbances caused by the combination of shallow waters and high winds are threatening the health of Iowa’s Storm Lake.
Although Storm Lake looks picturesque from a distance, the resuspension of sediment is affecting water clarity and exposing harmful nutrients in the water.
Led by Clayton Williams and John Downing, professors in Iowa State University’s Department of Ecology, Evolution and Organismal Biology, a research team has begun monitoring the lake to determine the causes and potential solutions to the lake’s sediment issues.Read More
Researchers at Clemson University will help the South Carolina Department of Transportation monitor pollutants discharged from construction sites, according to a release . The state agency wants to make sure it is ready for future federal pollution requirements.
Turbidity monitoring near active SCDOT construction sites will judge the effectiveness of the agency’s stormwater runoff protocols. SCDOT will then design enhanced methods to better control runoff from construction sites.
Heavy metals, toxic substances and biological pollutants are all associated with runoff from the sites. The study to find better ways to manage the pollutants is funded by a three-year grant from the federal government.Read More
