A potentiometric sensor for measuring oxygen activity in LBE has been developed since 2000 until today at 'Institut Quimic de Sarria' electrochemistry laboratories. This sensor is based on In/In3O 3 reference electrode. The last experiments performed with this sensor have been directed to characterise the sensor. For this purpose, the following experiments in stagnant conditions have been performed: effect of the operating temperature from 300 to 500°C, different covering gases (N 2 + 5% H2, Ar 99.999%, and N2 + 10 mg/L O 2) and comparison of different solid electrolytes (ZrO /Y2O3 and ZrO2/MgO). Long-term experiments have also been performed to the see the stability of the signal with time.
