Electrodes for the combined measurement of oxygen and carbon dioxide
First Claim
1. An electrode arrangement for the combined measurement of the partial O2 and CO2 pressures of a medium, the arrangement comprising measuring electrodes, one of which applies for PO2 and the other applies for PCO2, a reference electrode, a diaphragm covering the electrodes and an electrolyte layer between the electrodes and the diaphragm, the reference electrode has disposed thereon a layer of gold which is at the same potential as the reference electrode and the electrolyte contains a predetermined concentration of a soluble silver compound or of a silver complex.
