When we're not using the pH meter, we put pH meter storage solution (Hanna HI70300L shown in picture) in the cap to keep the electrode from deteriorating. Water (even distilled or RO water) should not be used for storage.

Make sure to rinse the meter well before using to wash off all storage solution. Rinsing with regular tap water is fine if you intend to use the meter immediately.

There's no need to store the pH meter in pH meter storage solution in between measurements on brew day. After using, simply rinse off the meter with distilled or RO water and shake dry. At the end of the brew day, rinse it again, fill the probe cap with storage solution and close. You may see some white crystals form on the outside after a day or two. This is normal and is storage solution that has seeped out a bit and dried. It can be left until the next brew day. If you don't plan on using the pH meter for a few months, check it periodically and add more storage solution as required.
