GALVANIC CELL TYPE OXYGEN SENSOR

摘要

Provided is a galvanic cell type oxygen sensor including a positive electrode, a negative electrode, an electrolyte solution, and a first oxygen permeable membrane, wherein the concentration of oxygen detected before ordinary use of the sensor is controlled into the range of 0.1 to 4.0% by volume both inclusive, or the output voltage of the sensor before ordinary use of the sensor is controlled into the range of 2.5 to 20% both inclusive of the output voltage thereof at the time of the ordinary use.
