Abstract
The invention relates to an RoHS-compliant galvanic oxygen sensor of a new type. Said RoHS-compliant galvanic oxygen sensor has a lead-free anode, preferably is backwards compatible with the existing lead-containing sensors in the remaining electrical and geometric specification and the service life of the RoHS-compliant galvanic oxygen sensor, and has no cross-sensitivity to nitrous oxide. The RoHS-compliant galvanic oxygen sensor having a lead-free anode comprises a housing (), a tin-containing anode (), a diffusion barrier (), a cathode (), and an alkaline electrolyte (). An aqueous solution of metal salts is used as the electrolyte, wherein a catalyst poison preferably is added to the electrolyte.
