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. -
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.
