Hi to all,
I do not know what is exactly the type of your probe but these storage routine 
should apply for most of electrodes (some of it you have quoted before):

What I do remember for sure is that if you want to get a proper accurate 
results, you should/have to calibrate the probe each time when you use it and 
that should be done against a reference "buffers" of exactly known pH

I guess that you know the stuff just be careful because an accurate and 
functional pH probe was quite a challenge even in a well establish laboratories 
and "very exact protocols" were applied. I guess that Glen or his colleges may 
know more.

Best of luck,

Frantisek
