Advanced oxygen sensor with oxide electrode materials

Calcium doped lanthanum and yttrium manganite electrode materials with oxygen deficiency and low polarization resistance (&#60;30Ωcm<sup>2</sup> at 600°C) were tested in new advanced electrochemical sensor for the oxygen measurements. Oxygen sensor with oxide electrodes was showing fast response (t<inf>95</inf>∼5s at 600°C), good reproducibility (±0.04% O<inf>2</inf>) and long term stability at different oxygen concentration.
