How should I store my pH probe?
pH probes with glass electrodes need to be stored wet. An Electrode Storage Solution will work best for this, but a pH 4 or 7 buffer or even tap water will in most cases work for short term storage. Never use distilled or deionized water for storage, only use it for rinsing off the electrode. If the pH probe is an ISFET or silicone chip electrode, then it can be stored dry.
What happens if I let my glass pH electrode dry out?
