Frequently Asked Questions (FAQ)
Q1: Do electrode protection caps need to be replaced regularly?
It is recommended to replace them after each electrode maintenance or long-term storage to ensure the protection cap is clean and leak-free.
Q2: Can pH buffer solutions be reused?
Reuse is not recommended to avoid contamination affecting calibration accuracy. Use as soon as possible after opening.
Q3: How often should KCl electrolyte be replaced?
Usually every 1-3 months, or as determined by the measurement environment and the electrode instruction manual.
