YSI ProQuatro Multi-Parameter Water Quality Meter

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.

Monitoring Aquatic Ecosystems: How Science Drives Waterway Management in Northwest Georgia

The University of Georgia is home to multiple labs that focus on monitoring aquatic ecosystems and organisms across the state. The River Basin Center connects these monitoring efforts with external partners, including government agencies and NGOs, to inform management and restoration of the state’s waterways. Phillip Bumpers is a Postdoctoral Associate in the Rosemond lab and the Wenger lab at the Odum School of Ecology and an affiliate of the River Basin Center. An aquatic ecologist, Bumpers’ research focuses on quantifying how environmental variability shapes aquatic ecosystems and understanding the drivers of these trends. Monitoring Aquatic Ecosystems in Northwestern Georgia Recently, Bumpers and Dr.

Long-Term Monitoring in the Chautauqua Lake Watershed

With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.

YSI ProQuatro Multi-Parameter Water Quality Meter Review

When environmental professionals need a reliable multi-parameter meter with measurement flexibility, the YSI ProQuatro is an affordable option. The YSI meter measures a combination of water temperature, conductivity, pH, ORP, ammonium, nitrate and chloride. Sensors plug into a 4-port bulkhead with an included temperature/conductivity probe. Dissolved oxygen sensors, pH and/or ORP sensors are often selected for the other ports. Alternatively, the ion selective electrodes (ISE’s) ammonium, nitrate and chloride can be installed, though these are less common as frequent calibration is required.
