FAQ

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.
