Abstract (en)
[origin: DE4439898A1] The invention relates to an electrochemical measuring probe for determining the oxygen content of gases, especially that of internal combustion engine exhaust gases, with a tubular sensor component with, on the outside, a measuring electrode exposed to the gas to be measured and on the inside a reference electrode exposed to a reference gas. The reference electrode (36) has an associated pump reference volume (58) with a coating (60) with a high gas diffusion resistance.
