Modern and Efficient Design
The YSI EXO3 represents an advanced sonde platform that offers a wide range of capabilities to those dedicated to monitoring natural aquatic environments such as oceans, estuaries, rivers, lakes, and groundwater. With a highly efficient power management platform, robust construction, and chemistry-free anti-fouling system, the EXO3 allows accurate data collection for up to 90 days between service intervals.
Multi-Port Water Quality Sonde
The YSI EXO3 sonde includes four sensor ports and a central anti-fouling wiper option. Sensor (sold separately) parameters include:
- Temperature
- Conductivity
- Depth
- Dissolved oxygen
- pH
- ORP
- Total algae (phycocyanin or phycoerythrin along with chlorophyll)
- Turbidity
- Fluorescent dissolved organic matter (fDOM)
- Rhodamine WT
- UV nitrate
- ISE ammonium
- ISE nitrate
- ISE chloride
Outputs Four Calculated Parameters.
- Salinity
- Specific conductance
- Total dissolved solids (TDS)
- Total suspended solids (TSS)
Onboard Signal Processing and Memory
All EXO sensors are digital sensors with onboard signal processing and memory. Built-in sensor diagnostic and calibration data allow users to calibrate multiple sensors in one sonde and distribute them to various other sondes in the field. Wet-mateable connectors allow for swaps in wet conditions, while active port monitoring automatically detects each sensor and verifies operation.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania
Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Sustainable Data Collection: Climate Monitoring in the Caribbean
Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.

Protecting Chicago's Lakefront: Freshwater Beach Monitoring
Thousands of people flock to the Great Lakes every year to enjoy the freshwater beaches along the coast. As an urban hub with over 2.5 million residents, beachfronts in Chicago have regular visitors as well as tourists that recreate in the bordering Lake Michigan. According to the Chicago Park District, it is estimated that more than 100,000 residents and visitors per day use Chicago’s Lakefront trail during summer weekends. Proximity to the Lake is not only a recreational activity for Chicagoans, but also a part of the city’s history due to its role in domestic and international shipping routes. In addition, the Lake serves as a drinking water source and as an essential climate regulator in the region that acts as a natural air conditioning affect.
