Aanderaa - Salt Water Conductivity Sensors

Water Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring conductivity of water. 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. This means that, together with temperature and depth information, a good estimate of the salinity may be determined. By using the inductive principle, stable measurement can be obtained with­out utilizing electrodes that are easily fouled and may wear out in the field.
