Clark electrode

The Clark electrode is an electrode that measures ambient oxygen partial pressure 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.
