Which Thermo Star DO meter has better reading ranges?
All three meters (A213, A323. and A223) have the same dissolved oxygen range using either an RDO optical dissolved oxygen probe or a polarographic dissolved oxygen probe.
|
|
Will my meter read dissolved oxygen in percent saturation?
The Star A223 will display dissolved oxygen in percent air saturation or concentration.
|
|
Does the kit come with an optical probe or a polarographic probe?
The Thermo Orion Star kit (STARA2235) comes with an optical DO probe.

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.

Bacterium Breaks Down Ammonium in Sewage and Runoff Without Oxygen
Wetlands are one of nature's plans for treating water. Home to a host of different microbes, riparian wetland soils play matchmaker to nutrient-rich runoff and bacteria that feast on nutrients and other environmental toxins. Princeton University researchers have discovered one such bacterium—Acidimicrobiaceae bacterium A6—that can break down ammonium, part of both fertilizer and sewage runoff, without oxygen. This ability could mean wastewater treatment without expensive aeration machinery. Peter Jaffé , Princeton's William L. Knapp '47 Professor of Civil Engineering and a professor at Princeton's Andlinger Center for Energy and the Environment , corresponded with EM about the latest research . Dr. Jaffé and his team first published on A6 in 2015.

Monitoring and Tracking Ocean Microbes with LRAUVs
In March and April of 2018, researchers from the University of Hawai'i at Mānoa (UH Mānoa) and the Monterey Bay Aquarium Research Institute (MBARI) deployed a small fleet of long-range autonomous underwater vehicles (LRAUVs) in the waters of the Pacific near Hawaii. These LRAUVs automatically collect and archive samples of seawater, enabling scientists to study and track ocean microbes with a level of detail that is unprecedented. Chasing eddies The team who undertook the expedition on the research vessel Falkor was hoping to survey and track Mesoscale eddies within the North Pacific Subtropical Gyre (NPSG) using a suite of oceanographic instruments.
