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, tripod, and c-clamp.

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).

After 10 Years, Great Lakes Monitoring Program Still Adapting

The public knows much more about Great Lakes coastal wetlands than it did ten years ago.  In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system. “I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor. The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.

Thin Ice: Year-Long Monitoring in Missouri Reservoirs

The value of multi-lake studies is well understood by international organizations like the Global Lake Ecological Observatory Network (GLEON) and the scientists who work tirelessly to provide data to the larger network. Rebecca North, an associate professor at the University of Missouri-Columbia , is one of many researchers involved in multi-lake research initiatives and conducting research locally in her home state. Having been born and raised on the shore of Lake Ontario, North grew up in a community that revolved around water. She also saw firsthand one of the worst water quality bodies of the world, the Bay of Quinte, decline throughout her lifetime.

Duality of Science: The Importance of Science Communication for Promoting Change

It is no secret that in today's world, most scientists do not stick exclusively to science–they must be educators, communicators, and advocates. The looming threats facing the planet's climate and the growing distrust in science by the public have forced scientists to expand and improve their capacity for science communication to the world.  From repeatedly testifying before the U.S. Congress to winning an Emmy as the Chief Scientific Advisor for an award-winning nature documentary, marine ecologist James W. Porter has been thrust into the public eye.
