YSI ProDSS - Digital Sampling System
YSI’s ProDSS is a revolutionary handheld instrument for water quality spot-sampling and profiling in the most demanding field conditions. The ProDSS is the most advanced handheld instrument available and can measure a wide range of parameters including dissolved oxygen (optical), pH, ORP, turbidity, conductivity, temperature, depth, nitrate, chloride, ammonium and more.
Digital Sampling System - Smart and Easy-to-Use
The ProDSS is a digital instrument with smart sensors that store calibration information and are auto-recognized by the instrument. Any sensor can be installed in any of the 4 sensor ports, allowing for measurement of any combination of parameters. The ProDSS handheld features a menu-driven user interface and an on-board help key/function.
Advanced Features and Durable Design
The ProDSS features a graphic, backlit, color display and a backlit keypad for visibility and easy menu navigation in all lighting conditions. The ProDSS utilizes a rechargeable lithium-ion battery pack. The ProDSS can be ordered with or without built-in GPS. GPS coordinates can be stored with measurement data for geo-mapping in the provided PC data management software, KorDSS. The instrument features a rugged, waterproof case (IP-67 rated) with rubber over-mold and metal, military-spec (MS) cable connectors.
Customizable
The ProDSS handheld, cable (cable management kit included with 10, 20, and 30 meter cables) and sensors are sold separately to provide you many options when “building” a ProDSS. The handheld features optional built-in GPS capability while the cables (up to 100 meters) have an optional depth sensor. A whole suite of accessories are also available to complete your system.
Download Data to PC or Transfer to USB Stick
The ProDSS features a built-in micro USB On-The-Go port for connection to a PC or USB stick. KorDSS software, a powerful PC data management program for the ProDSS, is included with each instrument. The ProDSS internal memory allows for logging > 100,000 data sets, plus 100 sites, 100 Data IDs and 400 GLP records.

The ProDSS uses a rechargeable Lithium-Ion battery pack that lasts 48 hours with the instrument alone and about 20 hours with the instrument and fully loaded cable assembly.
The ProDSS, like the Pro Plus, is a multi-parameter meter. The advantage of the ProDSS is that it can measure turbidity and optical dissolved oxygen, whereas the Pro Plus does not support turbidity and uses electrochemical dissolved oxygen. The ProDSS also has optional depth and GPS.
The “Smart” Sensor holds the calibration in the sensor, so it can be moved from meter to meter without needing to recalibrate.
When ordered from Fondriest Environmental, all YSI sampling equipment is assembled and calibrated prior to shipment at no cost and includes a calibration report.
The ProDSS includes a USB memory stick containing Kor Software and PDF manual. Kor Software is an easy-to-use platform full of features for managing YSI instrumentation and water quality data. View live or recorded data, calibrate sensors, setup long-term deployments, and ensure equipment is operating at peak performance.
No, cable assemblies and sensors are sold separately.

Everglades Restoration: A Story of Wetlands and Water
The Everglades are famous as a popular tourist destination. In 2019, over one million people visited the famous national park that makes up their southern portion. They are also famous, though probably less so, for ongoing, large-scale restoration efforts aiming to restore some of the hydrology that earned the system the nickname the River of Grass. 
 
"Restoring the River of Grass to something closer to its former state will provide timely relief for vital wetlands that support wildlife, industry and the 8 million people that utilize the Everglades for the fresh water they provide.

This summer a new way to learn about water recreation—and environmental stewardship—paddled into Ohio. With the help of the Toledo Metropolitan Area Council of Governments (TMACOG) , the US Environmental Protection Agency's (US EPA's) Urban Waters Program brought the Wilderness Inquiry Canoemobile “floating classroom” to Toledo for a few days. 
 
 TMACOG Water Quality Planner Sara Guiher spoke to EM about the programming and the experience. 
 
 “In August of 2018 we spoke with a representative from US EPA Urban Waters,” explains Guiher. “We received funding through them to bring programming to the area focused on urban water resources. The person that we talked to from US EPA suggested Canoemobile, which we had never heard of.

Named after French royalty, Dauphin Island sits on the Gulf of Mexico. It is an important stop for many migratory birds traveling from South America as well as many human visitors in search of beach scenery. It is also home to the Dauphin Island Sea Lab (DISL), which serves as the main educational and research center for marine science studies in Alabama. One of DISL's most impressive gems is the Estuarium, a large aquarium where the public can view estuarine organisms native to Alabama which includes a 12,500 square foot exhibit hall. Aquatic life from the Mobile-Tensaw River Delta, Mobile Bay, the Barrier Islands and the Northern Gulf of Mexico are featured. Outside the aquarium is the Living Marsh Boardwalk, which looks over Mobile Bay .
