EXO2s Multiparameter Sonde

EXO2s Multiparameter Water Quality Batteryless Sonde (7 sensor ports including a central wiper port) This equipment is available for rent

  • High-accuracy sensors with on-board memory
  • Wireless communications
  • Seamless integration into marine, estuarine, freshwater and ground water monitoring systems
  • Horizontal profiling where light weight is optimal
  • Smart Sondes and Sensors
  • Extremely versatile instrument, allowing the user to automatically configure a sonde with different sensor for different applications in minutes
Category:

The more maneuverable monitoring platform.

We have heard from customers who need the payload and capabilities of YSI’s best-in-class EXO2 sonde, but in spaces and places that can’t accommodate the EXO2. YSI EXO2s (shorty) is a customized, batteryless sonde that comes with the same warranty and capabilities as the EXO2, and is ideal for specialized applications such as:

  • Attachment to an AUV or aerial drone
  • Integration with a buoy
  • Horizontal profiling where light weight is optimal

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
