17. A combustion analyzer comprising:
an oxygen sensor configured to sense the presence of oxygen in a combustion process and generate a first sensor signal indicative of the concentration of oxygen in the combustion process;
a dual carbon monoxide-methane sensor configured to sense the presence of carbon monoxide or methane in the combustion process and generate a second sensor signal indicative of a concentration of carbon monoxide or a concentration of methane in the combustion process; and a controller configured to determine the concentration of oxygen based on the first signal and compare it to a threshold, wherein the controller selectively generates a control signal, based on the comparison, to heat the dual carbon monoxide-methane sensor to 600° C.
