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
