YSI EXO2s Multi-Parameter Water Quality Sonde
The YSI EXO2s is a compact, batteryless sonde that comes with the same capabilities as the EXO2, and is ideal for specialized applications where external power is supplied.
- Ideal for spot sampling or attachment to data buoys, AUV's, drones, etc.
- Smaller, lighter sondes can be deployed in tight spaces
- A more budget-friendly EXO without alkaline batteries
The YSI EXO2s 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. The YSI EXO2s is a compact, batteryless sonde that comes with the same capabilities as the EXO2, and is ideal for specialized applications where external power is supplied. With a highly efficient power management platform, robust construction, and a chemistry-free anti-fouling system, the YSI EXO2s allows accurate data collection for up to 90 days between service intervals.
Multi-Port Water Quality Sonde
The EXO2s sonde includes six sensor ports and a central anti-fouling wiper option. Sensor parameters include:
- Dissolved oxygen,
- Total algae (phycocyanin or phycoerythrin along with chlorophyll),
- Fluorescent dissolved organic matter (fDOM),
- Rhodamine WT,
- UV nitrate,
- ISE ammonium,
- ISE nitrate, and
- ISE chloride.
Outputs Four Calculated Parameters.
- 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.
