Zebra-Tech PONSEL DIGISENS Turbidity Sensor Hydro-Wiper
- Highly effective brush technology for both marine and fresh water
- Precision on-board clock for accurate wipe interval timing
- Simple sensor installation and operation with user-replaceable brush
|PON-01-SC-30||Self-contained Hydro-Wiper for PONSEL DIGISENS turbidity sensor, 30m depth rating|
|Usually ships in 1-2 weeks|
The Zebra-Tech Hydro-Wiper is a mechanical wiper system designed to fit easily to the PONSEL DIGISENS turbidity sensor. Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the sensor clean from bio-fouling and other unwanted deposits such as mud. The Hydro-Wiper reduces the need for costly site visits to manually clean the instrument, maintaining data integrity throughout long deployments.

The public knows much more about Great Lakes coastal wetlands than it did ten years ago.
In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system.
“I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor.
The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.Read More
You might be surprised to hear good news about the world’s oceans. The dominant narrative for years has been that the oceans’ sea life populations are on the brink of collapse.
But, according to research Ray Hilborn published in January in the Proceedings of the National Academy of Sciences, the ocean’s fisheries are bouncing back, provided that they’re well managed.
“The bottom line is that if fisheries are managed they are sustainable,” Hilborn, a professor at the University of Washington’s school of aquatic and fisheries sciences, told Environmental Monitor.
New evidence of recovery
After two decades of recovering fish populations, many of the world’s fisheries are stable or recovering, Hilborn’s research shows.Read More
Thousands of lakes in the northeastern United States are at risk of chloride contamination.
In a 17-state area from Minnesota to Missouri to Maine, elevated chloride levels in some of the region’s nearly 50,000 lakes are driven largely by landscape features that are cleared of snow and ice by road salt in the winter.
“The biggest driver of increasing chloride concentrations in these lakes was road density and development. The more developed a watershed, the more likely you are to have roads and parking lots,” said Hilary Dugan, an assistant professor in the Center for Limnology at University of Wisconsin—Madison.
Dugan is the lead author on a study examining the issue recently published in Environmental Science and Technology .Read More
