The waterproof, battery-operated Thermo Orion Star A222 portable conductivity meter stands up to the most demanding field applications and delivers over 800 hours of continuous operation. The meter can be calibrated manually or automatically using Thermo conductivity standards to make the setup process easy. It comes equipped with 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.
The rugged, user-friendly meter displays conductivity, TDS, salinity, resistivity and temperature readings on a large, backlit LCD screen, while icons provide quick updates on battery life, electrode status and calibration information. Simple button layout and on-screen messages simplify 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.

Birds, Fish and Shifting Sediment; How Lake Erie Buoys Measure It All
Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages. A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years. In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help. A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.

Much remains unknown about sharks. The Cal State Shark Lab wants to change that
Thirty years ago, white shark sightings near California’s beaches almost never happened. For Chris Lowe, who was a graduate student at California State University’s Shark Lab at the time, spying a dorsal fin from one of the ocean’s top predators was very rare. Prior to the mid-90’s, an expansive commercial fishing operation and the loss of marine animals decimated white shark populations. If their food wasn’t being hunted, sharks were getting caught in gill nets. At that point, they would be killed anyways before getting brought to the market to be sold. Then in 1994, California residents approved propositions that banned gillnets in state waters and enacted protections for the white shark.
