O 2 analyzers a magnetic field which attracts O 2 to measure the concentration. The O 2 causes movement of a suspended mirror within the analyzer which then changes the amount of light being reflected by that mirror onto a photocell. The amount of current required to move the mirror back to center is proportional to the O 2 concentration.
