What is the difference between the A122, A222 and A322? Don't they all measure conductivity?
Yes, the Thermo Orion Star A122, A222 and A322 are all portable conductivity meters. The A122 has a conductivity range of 0.1 uS/cm to 200 mS/cm while the A222 and A322 have a greater range from 0.1 uS/cm to 3000 mS/cm. The A122 will not automatically calculate salinity. The A322 allows for calibration editing. The A122 has a 50-point datalog memory, the A222 has a 1000-point time/date stamped memory and the A322 has a 5000-point time/date stamped memory.

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.

Buttonbush Swamps, Bald Eagles, Soras and More: Ashland University’s Black Fork River Wetlands Environmental Studies Center Showcases Wetlands Wildlife and Habitats
Growing from a 38-acre purchase in 1998 to 298 acres in 2004 to the 305 acres it encompasses today; the Black Fork River Wetlands features habitats not found just anywhere, including buttonbush swamp, swamp forest, marsh, riparian corridor and uplands habitats. Beavers make their homes there, as well as trumpeter swans, bald eagles, soras and sandhill cranes. While it may seem picturesque and undisturbed, it is in fact embattled due to human activity on all sides. “It’s a multi-use area,” says Jenna Binder, a visiting Assistant Professor in Ashland University’s Biology and Toxicology Department. “It’s strongly influenced by the heavy agriculture in this area of Ohio. Oil and gas industry fracking is also being done in the area.

AS IF: North Carolina Biological Station Inspires Researchers and Artists to New Heights
Biological field stations make it possible for researchers all over the country to conduct environmental research. While some field stations have artist residencies, art is typically not the main focus of the biological station. Not so at Bakersville, North Carolina’s new AS IF Center (Art + Science In The Field) , which just opened its doors in March 2018. At AS IF, researchers and artists are deliberately invited to commingle, collaborate and create new things together. Far from being on the periphery or existing as an afterthought, artists are considered to be on parity with researchers at AS IF, the one energized by the other’s perspective.
