ELECTRODE CARE AND MAINTENANCE

For best results, always keep the pH electrode bulb wet.
Store the pH bulb with electrode storage solution. Electrode
storage solution is available as part of the Palintest Electrode
Care Pack (see Accessories Section). If electrode storage
solution is not available, use tap water or buffer solution.
NEVER use deionised water for storage.
Wash the probes thoroughly with tap or distilled water
after each use.
Because your pH electrode is susceptible to contamination
or dirt, clean it every 1 to 3 months depending on extent
and condition of use.
