gas-sensing electrode
An electrode in which a gas-permeable membrane of the body separates the test solution from an aqueous electrode solution in contact with an ion-selective electrode.

Gas permeation of the membrane changes the chemical equilibrium within the electrolyte, and the ion-sensitive electrode detects this change.
