The YSI 5564A pH and combination pH/ORP sensors have an internal, battery-powered pre-amplifier for use in difficult environments. The amplified sensors are approximately 0.75" (1.91cm) longer than the Model 5564 pH or 5565 pH/ORP Sensors. The available extension adapter attaches to the bulkhead so the longer sensors fit in the probe guard. All YSI flow cells work normally with the new sensors.

Advantages include:
  • Elimination of potentially erratic readings in high static environments
  • Improved sensitivity and stability in applications with very cold waters and for applications requiring long cable lengths
  • Applications that require a long duration in the field where there is the potential for exposure of the connectors to moisture
  • Potentially longer life if used and stored properly;> 2 years
What's Included:
  • (1) YSI 5564A pH electrode
  • (1) Storage bottle with solution
  • (1) Instruction sheet
  • (1) Cleaning certificate

Ocean acidification: University of Washington's giant plastic bags help control research conditions

With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

NOAA Alaska buoy network to monitor North Pacific ocean acidification

National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. “We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

Boise River Watershed Watch Shows Volunteers Issues River Faces

Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.
