Key Features

User-replaceable cables and sensors (not included with meter purchase)
Real-time salinity compensation of DO measurements
Built-in micro USB port for easy data transfer to flash drive

Overview
The YSI ProQuatro, along with its Quatro cable, allows the use of 4-ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate creating an extremely powerful handheld multiparameter instrument. Sensors are not included in meter purchases.

Versatile
Connect any Professional Series cable and probe option to the instrument and use the convenient cable management kit to keep everything simple and organized. Cable options range from 1-, 4-, 10-, 20-, and 30-meter choices (up to 100-meters on DO-only cables). Use lab or field probes and switch between the two quickly. The ProQuatro makes an ideal lab BOD instrument with the proven self-stirring BOD probe (EPA Approved). A complete family of accessories also increases the versatility of the YSI ProQuatro. Choose among accessories including carrying cases, flow cells, cable weight, belt clip, and tripod.

Questions & Answers

Will the ProQuatro work with the older Quatro cable assemblies that shipped with the Pro Plus meters?

Yes, the ProQuatro meter is compatible with all Quatro cable assemblies regardless of when they were manufactured. It is also compatible with the Pro10, Pro20, Pro30, Pro1020, Pro1030, and Pro2030 cable assemblies.

The ProQuatro meter is reading “Probe Temp under range”. What can I do to troubleshoot?

First, check the cable connection and ensure the temperature sensor is clean. If that does not resolve the issue, contact the Fondriest Repair department customercare@fondriest.com

Does any conductivity standard come with the 5560 temp/conductivity probe?

The 5560 temperature and conductivity probe for the YSI ProQuatro does not include any calibration solutions, these will need to be purchased seperately.

Can YSI meters and probes be recycled?

Yes, YSI has a recycling program for old equipment. Find it here: https://www.ysi.com/customer-support/recycling-disposal

It says that the DO sensor needs to be setup on the ProQuatro meter before calibration, what does that include?

The dissolved oxygen probe set-up for the ProQuatro includes setting the sensor to 'enabled' on the meter as well as selecting the type of probe that is being installed (polarographic, galvanic).

What is the difference between the 1001 pH sensor and 1001A amplified pH sensor for the ProQuatro meter?

The 1001 pH sensor works well on the 1m and 4m cables in typical applications. The 1001A amplified pH sensor has an internal pre-amplifier for improved performance with longer cables, contaminated bulkheads, and very cold waters.

Is it possible to order a ProQuatro Field Kit with cable lengths other than 4m?

The ProQuatro Field Kits are only available with 4m cables. If longer or shorter cables are needed, then it's best to order the individual components (meter, cable assembly, sensors, carrying case). As a complimentary service, Fondriest Environmental will assemble the meter and calibrate it prior to shipment.

I need to perform water quality profiles in lakes deeper than 30m. Are longer cable lengths available?

The longest cable length available with the ProQuatro meter is 30m. If a longer cable is needed for lake profiling, we recommend considering the YSI ProDSS multi-parameter water quality meter with cable lengths up to 100m and optional integrated depth sensor.

Chesapeake Bay Sees Largest Oyster Reef Restoration in the World Completed

The largest oyster reef restoration in the world was recently completed in the United States’ largest estuary: the Chesapeake Bay. The project is the result of a 10-year, over $100 million commitment from local, state, and federal agencies to restore one of the bay’s most vital keystone species. The Chesapeake has lost 99% of its historic oyster numbers, with cascading negative effects on the entire bay ecosystem. “When it comes to oysters, we’re down to 1% of our historic number of oysters,” says NOAA’s Chesapeake Bay Oyster Restoration Program Manager Stephanie Westby. “And when you lose 99% of your oysters, you lose 99% of your reef habitat, and you lose 99% of everything.

How Ohio’s Inland Fisheries Research Unit Uses Science to Improve Fishing

Ohio is a state defined by its water bodies, with Lake Erie to the north and the Ohio River meandering along its southern and eastern border. Within these boundaries are the Buckeye State’s inland waterways, sporting over 60,000 miles of rivers and streams and 112,000 surface acres of lakes and reservoirs, according to the Ohio Division of Wildlife . This plethora of water also offers ample opportunities for anglers to pursue the variety of sportfish that can be found in Ohio. While Lake Erie is well-known for its recreational opportunities, Ohio’s inland waterways also provide plenty of opportunities to pursue everything from bluegill to catfish. These thousands of miles of water are monitored and researched by many agencies and organizations within the state.

Monitoring for a Cause: How Climate Change Impacts Freshwater Organisms in Southern Appalachia

Climate change and subsequent shifts in weather events are changing aquatic ecosystems across the world. Streams drying up in droughts, floods overflowing rivers and displacing freshwater organisms, climbing temperatures making environments unsuitable for native species, and other stressors are all changing key habitats and shaping populations in impacted regions like Southern Appalachia. Michael Gangloff, Professor of Biology at Appalachian State University, has been monitoring waterways and freshwater taxa under duress in the southeastern US for 27 years, measuring abundance, size, and condition of local taxa as well as quantifying changes to physical habitat conditions through long-term monitoring at established sites.
