EXO3s Multiparameter Sonde

**Specifications indicate typical performance and are subject to change. All sensors have a depth rating of 250 m (820 ft), except shallow- and medium-depth sensors, ammonium, chloride, and nitrate. The accuracy specification is attained immediately after calibration under controlled, stable environmental conditions. Performance in the natural environment may vary from the quoted specification. w.i.g. = whichever is greater EXO sensors are not compatible with YSI 6-Series sondes, sensors, or handhelds. ^1^Outputs 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 ^3^Accuracy 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 ^7^Within the environmental pH range of pH 4 to pH 10. ^8^On 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).
