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.

Handheld Cyanotoxin Detection Technology Prototype
In the battle against harmful algal blooms (HABs), time is important . The need for laboratory equipment and testing is a serious challenge for water managers. This issue caught the eye of Qingshan Wei , an assistant professor of chemical and biomolecular engineering at North Carolina State University . “Our research group is interested in developing low-cost sensors,” Wei told EM . “Recently we have been developing sensors for environmental monitoring, and cyanotoxins came to our attention .” Cyanobacteria, which generate HABs, are becoming a challenge across the US . They are a very serious problem in North Carolina, in part due to the weather.

Assessing Cumulative Risk From Water Pollutants
New research from scientists at the Environmental Working Group (EWG) shows that an approach that assesses cumulative risk from water contaminants could save lives. EWG senior scientist Tasha Stoiber spoke with EM about how the team developed the innovative new approach . “Our organization has worked extensively on tap water over the years, and an updated version of our tap water database was just released in 2017,” explains Dr. Stoiber. “We've been thinking about new ways to analyze that data.” Right now, the risk from contaminants in water quality is assessed one at a time—but that really doesn't comport with reality.
