title: Silver-silver chloride plunge electrode needles and chloriding monitor.
abstract: A plunge electrode is made from a hypodermic needle with one side cut open and multiple electrodes exposed from tip to base. A method for constructing chlorided silver electrode plunge needles is explained as well as problems associated with electrode chloriding. The small surface area of these electrodes makes empirical methods of chloriding difficult to use. A monitor was constructed for the testing and chloriding of a twelve-electrode plunge needle. This system continuously measures the impedance of the electrodes during chloriding.
