Question
How should the Pocket Pro and Pro+ meters be stored when not in use?
Summary
Pocket Pro and Pro+ meter storage
Answer
The pH models (including the Multi 1/2) and ORP models should be stored with a couple drops of tap water or deionized water in the cap to keep the bulb hydrated.

pH Electrode Storage Solution, 500 mL (Product # 2756549) is not recommended to use with the pocket pro testers. This is because the storage solution is 3M KCl and the pocket pro testers have a 4M KCl electrolyte. Storing in lower concentration storage solution will cause a mV offset decrease the life of the tester.

Temperature, conductivity and TDS  models can be stored dry.
