The YSI Pro1030 provides everything required in a handheld instrument to measure (sensors sold separately) pH or ORP, temperature, conductivity, specific conductance, salinity and total dissolved solids (TDS).


  • Built-in conductivity cell with user-replaceable pH or ORP sensors (sold separately)
  • Smart calibration routine allows easy calibrations with the press of a button
  • Graphic backlit display with 50 dataset storage
List Price $999.00

The YSI Pro 1030 features user-replaceable sensors (pH and ORP), cables, and the convenient calibration routine feature make the YSI Pro 1030 user-friendly. The feature set of the Pro1030 results in a low total cost of ownership over the life of the product and proves that it is smarter, tougher, and more versatile.

Mil-spec (military spec) connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests ensure that the instrument remains in hand to provide years of sampling even in the harshest field conditions.

Additional Features include:

  • A smart calibration routine remembers previous cal values and walks through the calibration
  • Stores 50 data sets
  • Available with 1, 4, 10, 20, or 30-meter cables (4-meter and longer cables include cable management kit)
  • View display with polarized sunglasses on

Questions & Answers
How long does the battery in the Pro1030 last?
The Pro1030 meter uses 2 alkaline C-cell batteries that provide up to 425 hours of battery life when not using the backlight feature. A low battery indicator will notify the user when there is an hour left of power.
What is the Conductivity Reference Temperature?
The Pro1030 meter features an adjustable conductivity reference temperature ranging from 15°C to 25°C.
Does the cable length affect accuracy?
Yes. The 1 and 4 meter cables are accurate within 1% or 1 uS/cm of the reading. The 10 meter and longer cables are accurate within 2% or 1 uS/cm, whichever is greater.

Warming Pacific releases methane equivalent to Deepwater Horizon spill each year

The ocean keeps secrets from surface to seafloor, and some even deeper still. A group of researchers from University of Washington discovered one such secret by accident — and their findings could change the scientific world’s understanding of climate change and its relation to the Pacific. “In 2013, we were preparing for a research expedition that had nothing to do with this,” said Evan Solomon, assistant professor of oceanography at UW. “We wanted to get a long-term record of bottom water temperature variability.” The team gathered conductivity, temperature and depth profiles off the Washington coast. A comparison with other research quickly revealed a long-term trend of warming in the area.

Watershed groups handing tech to volunteers for better citizen monitoring

Watershed protection groups across the country are collecting water quality data on waterways that might otherwise miss out on monitoring entirely. Some have found that, despite small staffs, they can compile more high-quality data by putting water quality sensors and other professional scientific instruments in the hands of volunteers. For organizations like the Santa Barbara Channelkeeper, the reasoning for equipping volunteers with electronic handheld meters is clear: "We really want the data that we're collecting to be utilized," said Ben Pitterle, director of the group's watershed and marine program.

In Sierra Nevada streams, researchers on the lookout for drought-threatened fish

In the parched hills of the Sierra Nevada, researchers are surveying drought-weakened streams to see what effects long-term dryness is having on fish populations in the region. Their findings so far have been less than stellar, with sparse numbers of fish being counted. Still, as data collection is progressing, the researchers, who work out of the University of California, Davis’ Center for Watershed Sciences, are gathering insights that could aid in conservation efforts that are expected to grapple with coming climate changes. The purposes of the investigation are two-fold. “If we ever get rain again, we want to see how well these areas are recovering from drought,” said Rebecca Quinones, a postdoctoral researcher at the center and leader of the project.
