The waterproof, battery-operated Thermo Orion Star A323 portable RDO/DO 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 Thermo Orion Star A323, provide over 800 hours of continuous operation so the instrument is ready when it's needed, where it's needed. Compatible with Orion polarographic and RDO optical probes, the meter displays reliable DO concentration, DO saturation 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. The Thermo Orion Star A323 supports several calibration methods and compensation options to produce accuracte readings, 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.

After 10 Years, Great Lakes Monitoring Program Still Adapting
The public knows much more about Great Lakes coastal wetlands than it did ten years ago. In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system. “I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor. The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.

Fisheries Management Drives Fish Populations Recovery
You might be surprised to hear good news about the world’s oceans. The dominant narrative for years has been that the oceans’ sea life populations are on the brink of collapse. But, according to research Ray Hilborn published in January in the Proceedings of the National Academy of Sciences, the ocean’s fisheries are bouncing back, provided that they’re well managed. “The bottom line is that if fisheries are managed they are sustainable,” Hilborn, a professor at the University of Washington’s school of aquatic and fisheries sciences, told Environmental Monitor. New evidence of recovery After two decades of recovering fish populations, many of the world’s fisheries are stable or recovering, Hilborn’s research shows.
