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

Monitoring Made Mobile

EXO makes it easy to view data in the field. The EXO Handheld offers a dedicated, streamlined interface to EXO sondes. EXO GO uses Bluetooth to connect any Windows OS device to a submerged EXO sonde.

**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.
w.i.g. = whichever is greater

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).
