An oxygen analyzer system (10) includes first and second internally calibrated sensors (12, 12') each for detecting oxygen levels, and a processing subsystem (22) responsive to the sensors. The processor is configured to calibrate the first sensor while the second sensor detects oxygen levels, and to calibrate the second sensor while -the first sensor detects oxygen levels. The processor is further configured to compare the oxygen level detected by the first internally calibrated oxygen sensor and the oxygen level detected by the second internally, calibrated oxygen sensor, to output an error signal if the oxygen levels detected by the first internally calibrated sensor differ from the oxygen level detected by the second internally calibrated oxygen sensor by a predetermined amount, and to output the oxygen level detected by either the first or second internally calibrated oxygen sensor if the oxygen levels detected thereby do not differ by a predetermined amount. |
