Thermo Orion Star A325 Portable pH/Conductivity Meter

The waterproof, battery-operated Thermo Orion Star A325 portable pH/conductivity meter stands up to the most demanding field applications to deliver the most advanced performance of any portable meter. Four AA batteries, included with purchase of the A325, provide over 800 hours of continuous operation so the instrument is ready when it's needed, where it's needed. The meter displays reliable pH, mV, RmV, conductivity, TDS, salinity, resistivity, and temperature readings on a large, backlit LCD screen and automatically locks in stable readings.

Thermo Orion Star A320 series portable meters provide the largest storage capacity available for time-stamped data points, which can be conveniently uploaded to a PC through the meter's USB and RS-232 ports. Automatic or 1 to 5 point manual calibration makes instrument setup simple, while icons provide quick updates on battery life, electrode status and calibration information. The simple button layout and on-screen messages also assist with calibration and explain setup menu choices.

Choosing The Right Thermo Portable For Your Project

With so many options in Thermo Scientific’s Orion Star A line, it can be difficult to narrow down which meter will best fulfill a project’s needs. One easy way to rule out some meters is by considering application type. For projects that rely largely on collecting samples in the field, a portable meter is clearly the way to go. But there’s still a handful of meters to choose from. To simplify making the right choice, we spoke with Ricki Hartwell, the global product manager for Thermo Scientific’s Orion Laboratory and Field Instruments. She recently shared her tips on choosing the right Thermo benchtop. Let’s take a look at her recommendations for selecting the right portable meter.

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.
