  • 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

  Sample 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

  If you're interested in our sonde with 6-ports for even more water quality monitoring capabilities, visit our EXO2 sonde.

  Add an EXO Factory Service Plan to your next sonde purchase and have the peace of mind that your new instrument is covered. Use today’s budget to protect your investment for years to come!

  **Specifications indicate typical performance and are subject to change. All sensors have a depth rating to 250 m (820 ft), except shallow and medium depth sensors, ammonium, chloride, and nitrate. Accuracy specification is attained immediately following calibration under controlled and stable environmental conditions. Performance in the natural environment may vary from quoted specification.

  EXO sensors are not compatible with YSI 6-Series sondes, sensors, or handheld.
  
  ¹Outputs of specific conductance (conductivity corrected to 25˚C) and total dissolved solids are also provided. See Calculated Parameters and footnote 11.
  ² Temperature accuracy traceable to NIST standards
  ³Accuracy specifications apply to conductivity levels of 0 to 100,000 μS/cm.
  ⁴ Relative to calibration gases
  ⁵ When transferred from air-saturated water to stirred deaerated water
  ⁶ When transferred from water-saturated air to Zobell solution
  ⁷Within the environmental pH range of pH 4 to pH 10.
  ⁸On transfer from water-saturated air to rapidly stirred air-saturated water at a specific conductance of 800 μS/cm at 20˚C; T63<5 seconds on transfer from water-saturated air to slowly-stirred air-saturated water.
  ⁹ Calibration: 1-, 2-, or 3-point, user-selectable
  ¹⁰ Performance based on 3-point calibration done with YSI AMCO-AEPA standards of 0, 124, and 1010 FNU. The same type of standard must be used for all calibration points.
  ¹¹ Values are automatically calculated from conductivity according to algorithms found in Standard Methods for the Examination of Water and Wastewater (Ed. 1989).
