Overview
The Thermo Orion Star A214 benchtop pH/ISE better is the ideal choice for any lab. The informative, backlit display shows pH, mV, RmV, ISE and temperature readings along with electrode status, time, date, sample ID, user ID and calibration points. For advanced users, features such as stability and averaging choices provide additional options. The meter is easy to set up and use while providing reliable measurement of pH and ionic concentrations for quality control and general analysis applications. Automatic pH calibration or 1 to 5 point manual calibration for pH and direct ion measurement ensures accuracy even at extremes of concentration.
Easy Integration
Thermo Orion Star A210 series benchtop meters provide a large storage capacity for time-stamped data points, which can be conveniently uploaded to a PC through the meter's USB and RS-232 ports. Complimentary data analysis software allows users to quickly view and manipulate data. Accuracy can be ensured through 5 point calibration and calibration editing features.

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.

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. 
 
Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.
