Details
The waterproof, battery-operated Thermo Orion Star A329 portable pH/ISE/conductivityRDO/DO meter stands up to the most demanding field applications to deliver the most comprehensive package and advanced performance of any portable meter. Four AA batteries, included with purchase of the A329, provide over 800 hours of continuous operation so the instrument is ready when it's needed, where it's needed. The meter displays reliable pH, mV, RmV, ISE, conductivity, TDS, salinity, resistivity, dissolved oxygen concentration, dissolved oxygen percent saturation and temperature readings on a large, backlit LCD screen and automatically locks in stable readings. Both Orion polarographic and RDO optical DO probes are compatible with the meter, as well as the extensive line of Orion pH, ISE, and conductivity electrodes.
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. Automatic or 1 to 5 point manual pH/ISE and conductivity calibration and a variety of DO calibration options make instrument setup simple, 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.

Is this the Thermo equivalent to the YSI Pro Plus?
The Thermo Orion Star A329 and the YSI Pro Plus are very similar. They will both measure pH/ORP, conductivity/salinity, temperature, dissolved oxygen and ISEs. For dissolved oxygen, the Star 329 meter can be used with an optical or polarographic probe. The Pro Plus, on the other hand, offers polarographic or galvanic DO sensors, but not optical. The Star A329 portable meter is compatible with ISE probes to measure sodium, fluoride and ammonia, while the Pro Plus offers ISE sensors for ammonium, chloride and nitrate. They are both portable and waterproof (IP67).

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.

Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

From Scrub-Jay DNA to Cycles of Carbon, Water and Fire: Archbold Biological Station Offers A Deep Look at Conservation
The oil industry is sometimes viewed as an enemy of conservation. But it was the oil industry that enabled the founding of Archbold Biological Station , one of the members of the Organization of Biological Field Stations (OBFS) . Descended from John Dustin Archbold, President of Standard Oil of New Jersey, Richard Archbold used his private wealth to further the cause of field research and education. He became an explorer, aviator and perhaps most importantly, a research associate with the American Museum of Natural History. He established Archbold Biological Station in 1941 after the father of his friend Donald Roebling (from a famous family himself), donated 1,058 acres of pristine land in the heart of Florida to further Archbold’s research dreams.
