YSI EXO1 Multi-Parameter Water Quality Sonde
The YSI EXO represents the next generation of water quality instruments from YSI. The EXO1 sonde includes four sensor ports with internal data logging and battery power.
- Titanium sensors with wet-mateable, universal sensor ports
- Compact sonde fits in 2" diameter groundwater wells
- Smart QC automatically checks for faults and errors to ensure successful deployments
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.
The EXO1 sonde includes four sensor ports with internal data logging and battery power. 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.
