I believe if it dries out it effectively loses its calibration.

 

I reference the below for all things pH meter related.

Distilled water will dilute probe reference liquid and response time will increase and reading would be unreliable.

 

Keep the probe wet and store is in storage solution.

Yes, that's the correct one.

Q:

 

A:

 
pH probes should never be stored in distilled water; it will cause the salts inside the probe to leech out, rendering it useless. Either storage solution or a buffer solution should be used.

Oh my goodness, I have been storing mine in RO water

 

Is there any other solution that I can store it in except the storage solution as mentioned in the amazon link, as we dont get it around where I stay?

 

You can store it in the pH 7 buffer solution.
