10 year old pH probe

[ataller]

I have a 10 year old pH probe that I got with my first gen Apex.
It still calibrates well and stays calibrated.
It tests correct against calibration fluid and matches my seneye precisely.

Should I call the Guinness book of world records ?

Maybe! That sounds like 5x longer than mine last.
