I would just like to add a word of caution: My experience of pH meters
is very mixed and I suggest that before you buy a flat electrode meter,
you test it on all the surfaces you might want to measure the pH of, [in
case it need to make the surfaces so wet it is unusable] and ask about
recalibration and indeed about drying out problems.
 
I would be very interested in the results of your research; I am sure
that pH meters have improved since I last looked at them.
