Abstract
The present disclosure sets forth improvements in a cleaning procedure to clean electrodes exposed to hypochlorite in a measuring device. Typical measuring electrodes are made of platinum, gold, silver or other conductive metals. The electrode is dipped in a strong acid bath, a sacrificial oxide coated titanium electrode is placed in the bath and a DC power source is connected between the metal electrode requiring protection and the sacrificial electrode to create current flow until the surface has been treated. Current flow accomplishes the treatment after which the electrode can be removed and used in measuring hypochlorite concentration.
