El Registrador de Datos (Data Logger) HOBO U24-002-C de Conductividad/Salinidad de alta precisión, con alta fiabilidad para mediciones de conductividad, salinidad y temperatura en ambientes de agua salada, bahías etc... 
El registrador reduce significativamente el costo para la monitorización de la conductividad/salinidad a la vez que se caracteriza por un facil mantenimiento. 

The HOBO U24-002-C is a cost-effective data logger for measuring salinity, conductivity and temperature in saltwater environments with relatively small changes in salinity (±5,000 μS/cm) such as saltwater bays, or to detect salinity events such as upwelling, rainstorm, and discharge events. It can also be used to gather salinity data for salinity compensation of HOBO U26 Dissolved Oxygen logger data.

Nota: Para monitorizar salinidad en eguas con +/-5,000 uS/cm de variación, referirse a las precisiones mostradas en el Plot C. See the product specifications to determine if the accuracy is acceptable for your needs. Monthly field calibration readings are typically required to achieve the best accuracy.

  • Non-contact sensor provides long life
  • Provides easy access to sensor for cleaning and shedding air bubbles
  • Two user-selectable ranges provide measurements from 100 to 55,000 uS/cm.
  • The Delrin housing will not corrode in saltwater
  • HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity using the Practical Salinity Scale 1978 (PSS-78)
  • USB optical interface provides high-speed, reliable salinity data offload in wet environments
  • Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport

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.
