The polarographic oxygen partial pressure sensor consists of two electrodes immersed in an electrolyte supported in a nylon case. The electrodes and electrolyte are separated from the atmosphere by a Teflon membrane. Oxygen passes through the membrane and is reduced at a noble metal electrode. This reduction produces a current proportional to the amount of oxygen present. At 100% oxygen the current is approximately 55 microamperes. Tests to determine the operating characteristics are discussed.
