|606150||6150 ROX optical dissolved oxygen sensor with self-cleaning wiper|| |
|Usually ships in 3-5 days|
Note: All optical DO membranes are now manufactured from anti-fouling copper alloy; these membranes directly replace black plastic membranes. Anti-fouling membranes can be used on existing ROX probes with no detrimental effects on data. The copper-alloy YSI 6155 optical DO membrane may arrive with surface patina and/or discoloration. This will not affect membrane performance.

A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch.
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.”
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.Read More
River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often.
Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing.
This summer a new way to learn about water recreation—and environmental stewardship—paddled into Ohio. With the help of the Toledo Metropolitan Area Council of Governments (TMACOG) , the US Environmental Protection Agency's (US EPA's) Urban Waters Program brought the Wilderness Inquiry Canoemobile “floating classroom” to Toledo for a few days.
TMACOG Water Quality Planner Sara Guiher spoke to EM about the programming and the experience.
“In August of 2018 we spoke with a representative from US EPA Urban Waters,” explains Guiher. “We received funding through them to bring programming to the area focused on urban water resources. The person that we talked to from US EPA suggested Canoemobile, which we had never heard of.Read More
