The comprehensive Thermo Orion Star A329 portable pH/ISE/Conductivity/RDO/DO meter provides lab-quality accuracy for advanced water quality readings in any location.
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).

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.
Read MoreWith 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.

They don't tweet—but now citizen scientists are Tweeting on their behalf as part of the Bay of Quinte Remedial Action Plan . Nestled just west of the Saint Lawrence River's head along the northern shore of Lake Ontario, the Bay of Quinte is about 350 kilometers west of Montreal and about 200 kilometers east of Toronto. It has long been a hub for tourism and has historically been one of the best sport fishing locations in North America. In recent times, though, the Bay has been under threat. Tweeting for the osprey In 1985, a Great Lakes watchdog designated the Bay of Quinte an Area of Concern.
