An electrochemical sensor is disclosed for determining the oxygen partial pressure, particularly in biological media in vivo. The arrangement includes a tubular flexible plastic member closed at one end which is permeable to oxygen and houses a pair of electrodes in a chamber portion thereof which contains an electrolyte. A portion of the chamber is filled with a sealing compound which partially embeds the electrodes, and the electrodes are arranged such that they project into the chamber at two different distances to be in contact with the electrolyte. The longer wire is provided with an insulating layer in the region over which the shorter wire extends. |
