- A galvanic cell using a commercially made calcium stabilized zirconia tube was used to measure the PO2 of analyzed and premixed gas mixtures of Ar-02 and CO-CO2 over a wide range of oxygen pressures near IOOO°C. The accuracy of the cell was evaluated by comparing these results with the reported analyses of these mixtures. A model based on thermal diffusion was used to explain the variation of the emf with flow at low flow rates. Errors due to a temperature difference across the electrolyte were also evaluated. When properly employed this cell has been shown to be a sensitive research device for the accurate measurement of the PO2 over a wide range of oxygen pressures.
