Reduced probe cell life may result if probe is operated continuously
above 1250°C (2282°F).
500 to 1000 ml/min. (1 to 2 ft
0.1s estimated
Refer to Fig. 5.1. The lower limit of operation, determined by the onset of electronic
conduction in the solid electrolyte is dependent on temperature. As a guide, the limits
are given in Table 8.1 for 1% electronic conduction but, in practice, it may be possible
to measure even lower oxygen potential levels without introducing significant errors.
