A simple, small galvanic cell oxygen detector employing a mesh-type electrode for the cathode is developed for use in gases. The detector is disk shape (3cm in diameter and 1cm thick) and consists of a Pb | KOH electrolyte | O2 cell in which a Teflon film is used as the oxygen permeable membrane. The cathode materials used are perforated Ag, Au and Pt sheets, and Ag wire gauzes (20-100mesh). Curves of current versus oxygen concentration in the range of 0.6 p, p. m. -100% O2 are given. It is found that the current generated is very stable and the operating life of the cell is considerably long. Results of continuous operation for several hundred hours in the laboratory atmosphere are shown. Data of open circuit voltage versus oxygen partial pressure for the cells of Ag, Au and Pt cathodes are presented and the electrode reactions are discussed.
