Abstract:
1. An electrochemical sensor for the determination of oxygen dissolved in an aqueous measuring medium, comprising: a working electrode and a counter electrode, an electrolyte layer arranged between the working electrode and the counter electrode, wherein the electrolyte layer comprises at least one particulate material and at least one binding agent which together form a porous, non-swellable framework structure, and wherein the pores of the non-swellable framework structure are intended to take up a liquid electrolyte or said pores contain said liquid electrolyte, and a gas-permeable cover layer arranged over the electrolyte layer, wherein the gas-permeable cover layer comprises at least one opening which enables a contact of a partial area of the electrolyte layer with the aqueous measuring medium, and wherein the opening is arranged at least partially over the area of the electrolyte layer that lies between the working electrode and the counter electrode.
