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.
