What is the effect of H2 in the background gas for the 9060?
If one of our sensors is in a gas composition with H2 as one of the components, and there is O2 present as well, there will be combustion of H2 at the surface of the zirconia sensor running at 720 degrees C. The result will be an equilibrium set up between the resulting O2, H2 and H2O. If the H2 is small in relation to the O2, there will be little effect on the O2 reading. If the H2 is much greater than the O2, the O2 will be reduced to concentrations in the order of E-22.
