YSI EXO2s Multi-Parameter Water Quality Sonde

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.

Features

  • 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

Details

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 EXO2s 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.
