1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Most commonly, a special type of conductivity, called specific conductivity, is used. Conductivity Technology. Conductivity and salinity are both measured by an electric probe on the data logger. This probe measures how much electrical current moves through the water. Salinity is then calculated from this value. Conductivity is determined by measuring how easily an electrical current flows between two metal plates.
