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.

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. [caption id="attachment_39045" align="aligncenter" width="940"] The YSI ProQuatro in use at the Fondriest Center for Environmental Studies.

Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. [caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

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.
