Question
How often is it recommended to clean laboratory pH electrodes?
Summary
pH electrode cleaning frequency.
Answer
The pH electrode manual includes cleaning as a troubleshooting step, indicating that cleaning would only be necessary if there are issues with the probe. However, routine cleaning is recommended to prolong probe life and prevent issues associated with a dirty electrode. The frequency of cleaning will vary from customer to customer based on frequency of use and application, but once a week is recommended to begin with.
