Abstract

A method for measurement of the concentration of a substance diffusable through inert membranes has a measuring electrode of metal, an electrolyte chamber containing electrolyte, a lipophilous membrane partially covering the measuring electrode and located between the measuring electrode and the electrolyte, and a reference electrode, wherein the substance is H.sub.2 O.sub.2, the combined membrane contains lipophilous ions and/or carrier-bound ions, the base membrane is proton impermeable, and the measuring electrode is formed as anode.
