<p>A digital oxygen analyzer is comprised of an oxygen sensor (10) connected to apply input signals to a dividing analog-to-digital converter (14). A thermistor (12) connected in the input circuit of the analyzer compensates for ambient thermal variations, and an absolute pressure transducer (16) coupled to the reference terminals of the analog-to-digital converter compensates for ambient pressure variation. A digital display (15) connected to the analog-to-digital converter indicates relative percentage of oxygen in the vicinity of the oxygen sensor.</p> |
