• Reference electrodes

For more information on these electrodes, see [1][2] .

• Normal hydrogen electrode (ENH)

By definition, this electrode serves as a reference for the potentials of the other electrodes used. Other reference electrodes have been developed for practical use.

Pt / H ₂ (activity = 1) / H ⁺ (activity = 1)

E = 0.000 V

• Saturated calomel electrode (ECS) (common use) [1]
