The waterproof, battery-operated Thermo Orion Star A223 portable RDO/DO meter stands up to the most demanding field applications and delivers over 800 hours of continuous operation. The informative, backlit display shows DO concentration, DO percent saturation and temperature readings along with time, date, sample ID, user ID and calibration information. The meter accepts both Orion polarographic probes and RDO optical probes for increased accuracy and versatility. For advanced users, features such as stability and averaging choices provide additional options.
Thermo Orion Star A220 series benchtop meters provide 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. Complimentary data analysis software allows users to quickly view and manipulate data. Accuracy can be ensured through a variety of pressure compensation options and calibration methods.

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.
The Star A223 will display dissolved oxygen in percent air saturation or concentration.
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.

Buoys in the time of Covid: Delays to important information
In early 2020, Michigan found itself facing one of the worst outbreaks of Covid-19 in the country. Though it’s close to second nature now, businesses, schools and governments were suddenly forced to conduct business without close contact. Universities and research institutions had to pause some scientific research. Whatever was able to continue slowed to a crawl. Around the Great Lakes, a network of buoys monitors dozens of water quality parameters and lake conditions, reporting them in real time. This year, the monitoring season was cut a bit short as Covid-19 restrictions hit in the weeks before buoys were set to be deployed.

Gar-Bage Fish No More. It’s Time to Respect Gar
Gar are a mean-looking fish, which along with their reputation as predators has earned them disregard and persecution for a long time. But that’s starting to change and it’s about time, says Solomon David, who’s watching with hope as gar are increasingly valued for their role in their ecosystems and as sport fish. “These attitudes are shifting, but there’s plenty of work to do,” said David, who is an assistant professor of biological sciences at Nicholls State University in Louisiana. While understanding of gar’s scientific and recreational value is increasing, gar still face the harmful effects of old beliefs and new challenges.
