Greenspan EC350 Electrical Conductivity Logger (DISCONTINUED)

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

Greenspan Electrical Conductivity Sensors use state of the art toroidal measuring system. Microprocessor technology provides accurate temperature compensated measurements. The EC sensor uses an electromagnetic field for measuring conductivity. The black plastic head contains two ferrite cores configured as transformers within an encapsulated open ended tube. One ferrite core is excited with a 10 KHz sinusoidal voltage which generates an electromagnetic field that surrounds both ferrite cores. The degree of coupling between the cores is inversely proportional to the resistivity of the coupling medium.
