Can I used distilled or deionized water to store my pH electrode?

You would think that pure or ultra-pure water would be the perfect way to maintain your electrode - but it is not.

No, never use this for storage it will damage the electrode. Storing in deionized (DI) water, or distilled water causes ions to leach from the glass membrane and reference electrolyte. Thus resulting in a slow and sluggish response.
