The EXO advanced water quality monitoring platform includes the versatile multiparameter YSI EXO2 sonde, a multiparameter 6-port water quality sonde or the YSI EXO1 sonde, a multiparameter 4-port water quality sonde, for estuarine, surface water, or ground water applications.

Key Benefits

  • High-accuracy sensors with on-board memory
  • Wireless communications
  • Fast response times for profiling and sampling
  • Seamless integration into marine, estuarine, freshwater and ground water monitoring systems

Smart Sondes and Sensors

Extremely versatile instrument, allowing the user to automatically configure a sonde with different sensor for different applications in minutes.

Accuracy

Tested in a variety of rigorous field conditions as well as lab conditions to ensure accuracy and response times

Monitor without Interruption

No matter which EXO sensors users select, other features of the sensors' design make them rugged and durable:

  • Wet-mateable connectors resist corrosion
  • Isolated components prevent short circuits
  • Welded housings and double o-rings prevent leaks
  • High-impact plastic and titanium resists breaking
  • Built-in antifouling systems protect data integrity
  • Low power consumption extends underwater deployments
