ABSTRACT:
Equipment for measuring the concentration of certain ions, particularly hydrogen ions, is disclosed. The ion sensitive electrodes used in this equipment are far more stable than those previously available. Many of the electrodes described use palladium hydride as the ion sensitive electrode and the electrode is stabilized by monitoring the hydrogen concentration in the palladium and replenishing automatically when necessary.
