Conductivity sensor

Salt Water Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring water conductivity. Measuring conductivity of salt water is a key parameter for in-situ measurements of several fundamental physical properties of water.

For saltwater, the ability to conduct electrical current is mostly dependent on temperature and the amount of inorganic dissolved solids. This means that, together with temperature and depth information, a good estimate of the water conductivity or salinity may be determined by measuring conductivity of water with an Aanderaaa conductivity sensor. Salinity is defined as the concentration of dissolved solids. By using the inductive principle, stable measurement can be obtained with­out utilizing electrodes that are easily fouled and may wear out in the field.

Other important properties of saltwater are again dependent on the salinity. Among these are the density and the speed of sound.

The Smart sensor, including the conductivity sensor  can be mounted directly on the top-end plate of the Aanderaa SmartGuard datalogger, in a String System node or connected to the SmartGuard datalogger and hence automatically detected and recognized.

Live Webinar: New High Accuracy Conductivity Sensor


Live webinar Recording introducing the New High Accuracy Conductivity Sensor 5819 from Aanderaa.

Aanderaa Conductivity Sensor


The New High Accuracy Conductivity Sensor from Aanderaa is now available. Built on the inductive principle, this sensor offers high initial accuracy of 0.004mS/cm, and lower drift at 0.001 mS/cm per month. This makes it ideal for applications requiring an accurate determination of conductivity, temperature, and salinity.
