Keep Electrode Hydrated
Ideally, pH electrodes should be kept in a storage solution when not in use. Placing the
electrode in a small glass filled with storagesolution is suitable. An option for pocket meters is to place a small piece of sponge into the meter’s cap and pour storage solution into the cap to wet the sponge.Pouring off any excess solution beforehand,the cap can then be placed on the meter.If a storage solution is not available the next best option is to use pH 4.01 buffer
(pH 7.01 is also suitable to a lesser extent).
Clean Electrodes Before Use
Clean the junction of your electrodes once a day or at least once a week to prevent junction clogging and to maintain accuracy. Immerse the electrode in the proper cleaning solution for at least 15 to 20 minutes. Hanna offers a wide range of cleaning solutions for general purpose and specific applications.
Replace Electrodes Once a Year
If your electrode takes too long to stabilize a reading, or readings fluctuate wildly, it is most likely time to replace the electrode. The typical life span of any pH electrode is from 6 months to 1.5 years.
