The Extech Oyster Series pH/mV/Temperature Meter features a large LCD built into the adjustable flip-up cover that displays pH or mV and temperature simultaneously. The microprocessor-based meter has a splash-proof housing and front panel tactile touchpad to slope and calibrate.

The meter measures pH from 0 to 14pH, mV from -999mV to 999mV, and temperature from 32.0°F to 212.0°F (0.0°C to 100.0°C). The memory function stores and recalls up to 25 labeled readings. Self-diagnostics display codes help users troubleshoot electrodes, buffer, and temperature errors. The measurements are automatically or manually temperature compensated, and the meter is calibrated at a 5-point buffer recognition (1.68, 4.00, 7.00, 10.00, 12.45) with adjustable values. An audible beeper will sound when a function is completed.

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.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania

Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.
