Zirconia O2 Measurment Principle

There are two different types of Zirconia measurement systems. 1      amperometric 2      potentiometric Figure shows a schematic of the amperometric system. An amperometric sensor consists of  zirconia cell that has a high voltage being applied across the two platinum electrodes. Oxygen then flows through  the diffusion hole and comes into contact with the cathode… Read More »
