Frequently Asked Questions
How to properly store the pH sensor?
It is recommended to store the sensor in KCl electrolyte to avoid drying out. Using protection caps can prevent damage to the sensitive membrane.
How often should standard solution and electrolyte be replaced?
Standard solution is recommended to be replaced monthly, and electrolyte every 1-3 months depending on usage frequency. For details, please refer to the sensor manual.
