caption_attribution_description: English: A schematic representation of Clark and Lyons' 1962 invention, the Oxygen Electrode
context_page_description: The Clark electrode is an electrode that measures ambient oxygen concentration in a liquid using a catalytic platinum surface according to the net reaction:
  O₂ + 4 e⁻ + 4 H⁺ → 2 H₂O
  It improves on a bare platinum electrode by use of a membrane to reduce fouling and metal plating onto the platinum.
