The electrical conductivity or specific conductance of a substance defines its capability to conduct an electric current. It is commonly signified by the Greek letter σ (sigma). The SI-unit is S/m (siemens per metre). The reciprocal of the conductivity is the electrical resistivity. They both can be easily measured with the Schmidt + Haensch Ash color turbidity analyser. This allows a fast and automated quality control of sugar as well as the turbidity analysis of liquids.
