ELECTROCHEMICAL SENSOR

摘要

An electrochemical sensor for the determination of the partial pressure of oxygen in a bloodstream comprising a cathode (20) and an anode (21) immersed in an electrolyte (17) contained in a chamber (23) defined by an oxygen gas permeable membrane (19) wherein the insulated portion of each of the conductors forming the cathode and the anode has an additional layer of insulation (24) applied over the original insulation.
