    Dissolved The probe is polarized with a fixed voltage of approximately 800 mV between the cathode and anode. Probe polarization is essential for stable measurements. Oxygen With the probe properly polarized, oxygen is continually consumed as it passes Setup through gas permeable PTFE membrane. If polarization is interrupted, the electrolyte solution continues to be enriched with oxygen until it reaches an equilibrium with the surrounding solution.
