Selection and Maintenance Recommendations
To ensure measurement accuracy, it is recommended to regularly replace the electrolyte and buffer solution and check whether the protective cap is intact. Here are some practical suggestions:
- Replace the electrolyte every 1-2 months, or adjust according to operating conditions.
- Use certified buffer solutions for calibration to ensure traceability.
- Install the protective cap when the electrode is not in use to prevent the sensitive membrane from drying out.
- Keep the sensitive membrane moist when storing the electrode.
Proper selection and maintenance can significantly extend electrode life and reduce downtime.
