The YSI EXO represents the next generation of water quality instruments from YSI. The advanced sonde platform 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, EXO allows accurate data collection for up to 90 days between service intervals.
The EXO2 sonde includes six sensor ports and a central anti-fouling wiper option. Sensor 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, and ISE chloride. The sonde can also output four calculated parameters including salinity, specific conductance, total dissolved solids (TDS) and total suspended solids (TSS).
All EXO sensors are digital sensors with on-board signal processing and memory. Built-in sensor diagnostic and calibration data allows users to calibrate multiple sensors in one sonde and distribute 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.

**Typically 90 days at 20ËšC at 15-minute logging interval; temperature/conductivity, pH/ORP, DO, and turbidity sensors installed on EXO1; or temperature/conductivity, pH/ORP, DO, total algae, and turbidity sensors installed with central wiper that rotates once per logging interval on EXO2. Battery life is heavily dependent on sensor configuration.
- (1) EXO2 sonde

Yes, the sonde is rated for salt water applications with the exception of the ammonium, nitrate, and chloride sensors that are freshwater only.
This is highly dependent on the deployment location, but re-calibration intervals typical range from 2 to 8 weeks.
No, only EXO sensors can be used with EXO sondes.
Up to three EXO2 sondes can be daisy-chained together using the Auxiliary port.
EXO1 and EXO2 sondes support SDI-12 communication through the use of the DCP adapter. EXO3 sondes have built-in SDI-12 support, so the DCP adapter is not necessary with EXO3.
All EXO sensors have a depth rating of 250m (820ft.) except shallow and medium depth sensors and ISEs.
While the battery life depends on the sensor configuration, the EXO2 can provide 90 days of logging at 15-minute intervals with temperature/conductivity, pH/ORP, DO, total algae, and turbidity sensors installed and the central wiper that rotates once per logging interval.
No, the EXO2 is slightly larger to accomodate the added sensor ports. The EXO2 sonde is 71.10cm in length and 7.62cm in diameter while the EXO1 Sonde is 64.77cm in length and 4.7cm in diameter.

Data Buoys Study Turbid Water Environments In Lake Erie Basin
What started as a study into a relatively unexamined type of cyanobacteria has turned biologists from Bowling Green State University into an integral part of the effort to monitor and protect the drinking water in Sandusky, Ohio. Dr. George Bullerjahn, the Professor of Research Excellence at Bowling Green State University, has done considerable work in the study of beneficial cyanobacterial organisms in the eastern and central basins of Lake Erie. His current project is focused on the growth of the toxic cyanobacterium Planktothrix in Sandusky Bay. Over the course of his career Bullerjahn has collaborated with Dr. Steven Wilhelm from the University of Tennessee.

Tracking Discharge From A Confined Disposal Facility
Getting things in place to monitor total suspended solids (TSS) around a dredging operation sometimes takes a quick turnaround. Just ask engineers at Tetra Tech who had short notice to get ready for tracking discharge out of a confined disposal facility (CDF) during the Avalon Back Bay Dredging Project. It’s entering what looks to be its final stage in 2016. Back in November 2014, they got approval to monitor during one of the early stages of the dredge work. But by the time they secured it, there was barely more than a week to get preparations underway. Luckily, they were able to rent the gear they needed just as dredging of areas in and around New Jersey’s Princeton Harbor began.

Forest Hydrology Study Considers Old Soil Effects
Soils in the Northern United States are relatively young compared to those to the south. This is thanks to the influence of glaciers, which receded only thousands of years ago to give soils in the region a chance to rebuild. Because of this history, soils in the Duke Forest, a large-scale living laboratory that supports a lot of research at Duke University, are some of the oldest on Earth. By comparison, they are millions of years old, easily outpacing their counterparts to the north. Perhaps unsurprisingly, these old soils, scientifically specified as ultisols (soils rich in red clay), hold a lot of mystery for researchers at the university. But that is also due to their intriguing influences on the ways water flows through the forest, its hydrology.
