YSI EXO-series Multiparameter Sonde

The EXO series is the successor of the popular 6-series from YSI. Each multiparameter sonde is rated to a depth of 250 meters. Parameters include: temperature, conductivity, depth, dissolved oxygen, pH, ORP, total algae (blue-green algae and chlorophyll in one sensor), turbidity, fDOM, plus 6 calculated parameters.


Smart sondes and sensors

“EXO was designed to be extremely versatile, allowing the user to configure a sonde for different applications in minutes. The key to this versatility is the smart sensors and smart ports,” explains Rob Ellison, YSI Director of R&D. “Each smart port is identical and automatically recognises any EXO sensor, so sensor payloads are designed by the user.”


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

 

For long-term monitoring programs, the data collected by EXO sensors are compatible with historic data from YSI 6-series sensors, helping users to maintain a consistent record of measurements.


Accuracy

EXO sensors and sondes are tested in a variety of rigorous field conditions, as well as lab conditions, to ensure accuracy and response times. Also, a new metrology system specifically for EXO offers improved accuracy of conductivity and temperature sensors to better address oceanographic challenges.

Applications

  • Long-term continuous monitoring
  • Vertical profiling
  • Underway monitoring
  • Integration into remote monitoring platforms
  • Source water monitoring
  • Ground water monitoring
  • Storm water monitoring
  • Dredging
  • Spot sampling
  • Stand-alone sensors

 

Key benefits

  • CTD plus 3-5 additional sensors in one small package
  • High-accuracy sensors with on-board memory
  • Wireless communications
  • Seamless integration into marine, estuarine, fresh water and ground water monitoring systems
