Measurements: Actual Conductivity, Temperature, Specific Conductance at 25C (calculated), Salinity (calculated using PSS-78, the Practical Salinity Scale 1978)
Conductivity Measurement Range: (Calibrated Range)
High Range: 5000 to 55,000 uS/cm
Low Range: 100 to 10,000 uS/cm
Over the range of 5 to 35C (41 to 95F)
Temperature Measurement Range: 5 to 35C (41 to 95F)
Resolution:Low Range: 3% of reading or 50 µS/cm, whichever is greater
High Range: 5% of reading, in waters within a range of
±3,000 µS/cm; waters with greater variation can have substantially greater error (see Plot C)
Conductivity: 2 uS/cm
Temperature: 0.01°C (typical 0.02°F)
Up to 12% sensor drift per month, exclusive of drift from fouling. Monthly start- and end-point calibration should be used with the HOBOware Conductivity Assistant to achieve the specified Specific Conductance accuracy.
