ELECTRODE APPARATUS FOR MEASURING PARTIAL PRESSURE OF MEDIUM

摘要

Oxygen partial pressure sensor with a measuring electrode (4) and a reference electrode (5), a membrane (8) covering the electrodes and an electrolyte layer (7) between the electrodes and the membrane, in which the electrolyte contains a defined concentration of a soluble silver compound or silver complex and the reference electrode (5) has a circular surface with a diameter of no more than a tenth of the diameter of the complete active area (6) of the sensor.
