A combustion analyzer configured to simultaneously detect the concentrations of oxygen, carbon monoxide and methane in a combustion process is provided. The combustion analyzer includes an oxygen sensor configured to detect the oxygen in the combustion process and generate a first sensor signal indicative of the concentration of oxygen in the combustion process. The combustion analyzer further includes a dual carbon monoxide-methane sensor configured to operate at approximately 600&#xb0; C. and provide a second sensor signal indicative of methane concentration and at approximately 300&#xb0; C. to selectively provide a third sensor signal indicative of carbon monoxide concentration. The combustion analyzer finally includes a controller configured to receive the sensor signals, determine the concentration of oxygen and generate a carbon monoxide concentration output and a methane concentration output based on the dual carbon monoxide-methane sensor signals and the concentration of oxygen.
