Abstract
An electrochemical measuring electrode has an ion-selective membrane and direct potential take off via an electron conductor. A diffusion barrier layer is provided between the membrane and the electron conductor for the purpose of reducing or eliminating the sensitivity to faults which can be caused by the presence of gases in a medium which is to be analyzed and into which the sensor is introduced. The diffusion barrier preferably comprises an ion-conducting solid-state body having a high diffusion resistance to oxygen.
