One of my engineer friends is curious how a pH meter accomplishes its task:
what's in the electrode; what is(are) the reaction(s) involved and what
produces the electrical signal; why is rinsing off the electrode judged
sufficient to avoid cross-contamination of samples (I seem to see a hole
through which SOMETHING could pass and get stuck)?
Anyone out there familiar with the nitty-gritty of these meters?

Thanks for your time,
Tim Merrill
