GAS SENSOR FOR MEASURING SOX

摘要

PROBLEM TO BE SOLVED: To provide a gas sensor for measuring SOx which is superior in response and can detect SOx of a lower concentration.

SOLUTION: A sub electrode 12 made of crystalline sulphate containing silver sulfate is formed on one surface of a substrate 11 made of a solid electrolyte material. A first electrode 13 containing silver is formed on the sub electrode 12 is formed. A second electrode 15 is formed on the other surface of the substrate 11. A gas introducing pipe 22 for introducing measuring gas is arranged such that one surface side of the substrate 11 is covered. A silica pipe is used for the gas introducing pipe 22.
