The YSI Pro 2030 is a handheld dissolved oxygen & conductivity meter that can simultaneously measure dissolved oxygen, salinity, conductivity, specific conductance, total dissolved solids (TDS), barometric pressure and temperature.

Long-Lasting and Quick Response
Offer fast response times with polarographic or galvanic DO sensor options. The long life of the polarographic sensor saves time and money, reducing overall cost. The galvanic sensor allows the user to start sampling immediately without a warm-up period. Both sensors offer accurate, quality data. The stable 4-electrode conductivity cell is built into the cable and will provide years of accurate data. The cells are designed for rugged field performance, are easily cleaned and require minimal maintenance.

Meets the Demands of True Field Work.
Rated to IP-67 standards even without the battery cover on. Other tough features include Mil-spec connectors and rubber over-molded case. In-house testing procedures also include 1m drop tests from all angles to ensure expected field-durability.

Additional Features Include:

  • Choose field DO sensors (Polarographic or Galvanic)
  • Stores 50 data sets
  • Graphic, backlit display and glow-in-the-dark keypad
  • Available with 1, 4, 10, 20, or 30m cables (4m and longer cables include cable management kit)
  • View display with polarized sunglasses on
  • Fastest DO response time on the market with 95% response in 8 seconds with standard membrane

Questions & Answers
Can I interface and transfer data to my computer with the Pro2030?
No, the YSI Pro2030 DO & Conductivity meter cannot be directly connected to a PC.
What if I need to calibrate the internal barometer?
The internal barometer in the YSI Pro2030 is calibrated at the factory. However, if this requires adjustment due to specific user location, a new value can be entered. This value should be the "true" local pressure, not corrected for sea level.
I want to purchase this meter with a 10 m cable and case. Which case should I get?
The 3075 carrying case is designed to carry a Pro Series meter with a 10 m or longer cable assembly. The 3074 is a hard-sided case that can carry either a Pro Series or 556 meter with a cable and flow cell. The 6262 case is used with a Pro Series meter and a 4 m or shorter cable assembly.
Does this handheld meter come with a hand strap or is it sold separately?
The YSI Pro2030 meter comes with the Pro2030 display, an adjustable hand strap, operations manual and quick start guide and (2) C-cell batteries.

Restoring Brook Trout Stream Habitat

Migrating fish species have it tough when it comes to getting back to their spawning grounds. Most of the time, they’re swimming against high-velocity currents and have to worry about passing through culverts and dams. But with the right mix of restoration projects, it’s possible to make things easier for these fish, as officials with the U.S. Fish and Wildlife Service (USFWS) know quite well. Crews with the agency in New York have been focusing in recent months on projects that can help brook trout, a fish that is held in high regard by anglers in the state. Before restoration work can take place, it’s important to know what streams, if improved, will provide the most benefits for brook trout.

Researchers pioneer continuous groundwater quality monitoring in Ontario

As a graduate student in Ontario, Jana Levison manually sampled groundwater wells in a hay field for a week straight. Now an assistant professor in the University of Guelph's School of Engineering, Levison is investigating how a new generation of water quality sensors can move the science forward while cutting the labor back. Levison said her doctoral work in a crystalline bedrock aquifer showed monthly variations in nitrate — a common groundwater contaminant often sourced to intensive agriculture — and daily variations in E. coli. Those short-term changes got her interested in watching groundwater in a more detailed manner. "Now we have the equipment that we can do that," Levison said. That equipment includes YSI's EXO multi-parameter sondes and Satlantic's SUNA nitrate sensor.

Data buoy on Acadia National Park's Jordan Pond to help answer clarity questions

Acadia National Park, the oldest national park east of the Mississippi, sits off Maine's Atlantic coast and covers most of Mount Desert Island — an unlikely name for a landmass covered in lakes and ponds. One of those is Jordan Pond, the deepest on the island, which is a famously clear lake in a state famous for clear lakes. "Jordan Pond is historically one of the most transparent lakes in Maine--or at least that's what they claim," said Nora Theodore, a masters student in ecology and environmental science at the University of Maine. And though the lake remains incredibly clear, decades of monitoring show the clarity is trending downward. "It's an extremely low productivity system, but that's been changing," she said. Transparency in Jordan Pond has been in decline since the 1990s.
