ABSTRACT:
A polarographic sensor device to determine the partial pressure of a gas in a sample medium is disclosed. The device comprises a) a substantially hydroscopic electrolyte composition joining a pair of spaced apart electrodes, one of the pair of electrodes being a sensing electrode; b) a membrane permeable to gas but impermeable to the electrolyte, the membrane having a front section for separating the electrodes and the electrolyte from the sample medium; and c) a fastener comprising a sleeve having a body portion and a lip, the body portion retaining the fastener and a side section of the membrane, and the lip retaining a portion of the front section of the membrane and holding substantially the entire front section in a spaced apart relationship from the sensing electrode.
