Abstract
An electrode for polarographic measurement of the partial pressure of oxygen in gases or solutions, comprising a cathode in contact with and outwardly shielded by a gas permeable membrane, a silver/silver bromide half cell serving as anode, and a bromide-containing aqueous electrolyte in contact with the anode and the cathode, the bromide ion concentration of the electrolyte being between 10.sup.-4 and 5 .times. 10.sup.-3 M, preferably 5 - 6 .times. 10.sup.-4 M.
