When should I replace the membrane and electrolyte in my polarographic DO sensor?The frequency of membrane and electrolyte replacement is process specific and will vary. Routine calibration before each run can identify a high nA current at the nitrogen zero point or low nA current in air, indicating a need to replace the membrane and electrolyte. Click to learn more about membrane replacement.
Does carbon dioxide sparging impact my DO measurement?CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed.
How should I store my polarographic DO sensor?For short term storage (< 1 month), polarographic DO sensors should be stored wet in electrolyte solution with the membrane immersed in a watering cap. For long term storage (> 1 month), remove internal electrolyte, rinse cathode and membrane in deionized water, and store dry. Click to reference the storage document for more information.
