The detection range of this galvanic oxygen sensor for oxygen concentration was 0.0% to 20.0%. By using gold or silver as cathode, reproducible response time and sensitivity to change of oxygen concentration were observed. The anode was Pb-Sn-Ca alloy. Oxygen selective permeable membrane was hydrophobic and porous Teflon film. The effect of the membranes varying in thickness have been studied on the temperature(<TEX>$10{\sim}50^{\circ}C$</TEX>) and relative humidity(R. H 0~99%). Lead acetate buffer solution as the electrolyte has shown a high output voltage and longer life.
