The membrane conductivity cell, MCC, is designed to measure ionic conductivity by simply
loading a membrane into cell hardware. The MCC adopts 4 point probe for measuring
conductivity. By passing current through two outer electrodes and measuring the voltage
through the inner electrodes, it allows the measurement of the conductivity.
In the 4-electrode configuration, there is virtually no current flow at the inner voltage
sensing electrodes. Therefore, polarization does not occur. The second benefit of the
4-electrode sensor is its tolerance of electrode coating. Since the 4-electrode technique
measures potential drop rather than resistance, the measurement remains accurate,
despite minor coating. The 2 probe measurement is also available by attaching the
working and sensing electrical connections to the cathode side while attaching the
counter and reference electrical connections to the anode side.
