Conductivity Measurements
|
Measurement Range |
Electrical conductivity and specific conductance: 0 to 100,000 µS/cm Salinity using PSS-78: 2 to 42 PSU Total Dissolved Solids (TDS): 0 to 100,000 mg/L |
Calibrated Range |
Electrical conductivity: 50 to 80,000 µS/cm | 5° to 35°C (41° to 95°F) |
Accuracy |
Conductivity: +/-2% or 15 µS/cm whichever is greater Salinity: +/-2% of reading or 0.1 PSU, whichever is greater |
Resolution |
Conductivity: 0.1 µS/cm from 0 to 1,000 µS/cm 1 µS/cm from 1,000 to 10,000 µS/cm 10 µS/cm from 10,000 to 100,000 µS/cm Salinity: 0.01 PSU TDS: 0.1 mg/L |
