Nota: Para monitorar a salinidade em eguas com +/- 5.000 uS / cm de variação, consulte as precisões mostradas no Gráfico C. Consulte as especificações do produto para determinar se a precisão é aceitável para suas necessidades. Normalmente, as leituras de calibração de campo mensais são necessárias para obter a melhor precisão.
Medidas: Actual Conductivity, Temperature, Specific Conductance at 25C (calculated), Salinity (calculated using PSS-78, the Practical Salinity Scale 1978)
Rango de Medida de conductividad: (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)
Rango de medida de Temperatura: 5 to 35C (41 to 95F)
Plot A: Salinity Range (U24-002-C)* |
Plot B: Specific Conductance Range in Saltwater |
Plot C: Specific Conductance High-Range Accuracy (U24-002-C) |
Precisión de Conductancia Específica: (in Calibrated Range using Conductivity Assistant and Calibration Measurements)
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)
Resolución:
Conductivity: 2 uS/cm
Temperature: 0.01°C (typical 0.02°F)
Conductivity Drift:
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.
Response time: 1 second to 90% of change (in water)
Operating Range: -2 to 36C (28 to 97F) – non-freezing
Memory: 18,500 temperature and conductivity measurements when using one conductivity range; 14,400 sets of measurements when using both conductivity ranges (64kbytes)
Sample rate: 1 second to 18 hrs, fixed or multiple-rate sampling with up to 8 user-defined sampling intervals
Clock accuracy: +/- 1 minute per month
