Mettler Toledo Sensor Conductivity 752-6mm Unit EA. This electrode is installed into a conductivity cell where it is connected to a processing module that measures the conductivity of the water. The electrode changes color from blue to yellow when the electrical conductivity of the water changes. The color change has no effect on the measured conductivity value. The electrodes are made of a special alloy that makes the sensors last longer. Electrodes are gold plated to provide an optimum conductivity measurement.
