Pseudo reference electrodes

Pseudo-reference electrodes are simply metal wires immersed in the sample solution. Although such electrodes do provide a constant potential, the reference potential is unknown, and is dependent on the composition of the sample solution These are pseudo reference electrodes which can be used to monitor cathodic protection systems but the potential of the electrode is dependent on oxygen levels and pH in the concrete. Calibration certificates cannot be provided for these electrodes. A data sheet can be found in the panel on the right of this page
