The YSI 1001A amplified pH sensor has an internal, battery-powered pre-amplifier for use in difficult environments.
Features
- Elimination of potentially erratic readings in high static environments
- Improved sensitivity and stability in very cold waters and long cable lengths
- Potentially longer life if used and stored properly; > 2 years
- Free ground shipping
- Expedited repair and warranty service
- Lifetime technical support

Overview
The YSI 1001A amplified 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 1001 pH or 1003 pH/ORP Sensors. The available extension adapter attaches to the bulkhead, so longer sensors fit in the probe guard for the Pro1010 and Pro1020 cables (not needed on the Pro Plus Quatro cable). All YSI flow cells work normally with the new sensors.
Benefits
- 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
- (1) YSI 1001A 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.

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.

Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.
