I've been searching this forum for info on pH meters since I've not been happy with my brews since going to water profiles built from RO. I have used water profile spreadsheets for mineral additions, but that's no substitute for an actual measurement.
I'm looking at the most recommended meters in the $100 dollar range, and see that the lifetime of the electrodes is generally stated to be a year or two. Replacements seem to be around $40.
My question is what wears out the electrode? Is it usage or is it shelf life? I brew around 6-8 times a year and it seems strange that I may only get a dozen or so uses per electrode. Is this what I should actually expect?
Also, what should I do to ensure the longest electrode life possible?
