My sample gas contains hydrocarbons and/or hydrogen along with trace levels of oxygen. Can I use an oxygen analyzer with a zirconium oxide sensor?
For applications where reducing gases such as hydrocarbons, carbon monoxide, hydrogen, etc. are present, zirconium oxide sensors should never be used. The sensors operate at temperatures of approximately 600 degrees. With the use of platinum electrodes, the presence of the aforementioned gases will interfere with the oxygen measurement resulting in lower than actual readings. Oxygen readings may be affected as much as 50% or greater, depending on the concentration of reducing gases.
