Abstract
This invention provides a polarographic/amperometric measuring sensor, particularly useful for transcutaneous determination of the oxygen partial pressure (tcpO.sub.2) in the blood by means of a Clark-type electrode arrangement. According to the invention the counter electrode, preferably made of a noble metal, is disposed about the insulating material encasing the working electrode and is preferably made of the same noble metal as the working electrode. The measuring sensor can also be provided with a pH electrode for simultaneous determination of the carbon dioxide partial pressure (tcpCO.sub.2) in the blood.
