Reg,
Here is the FAQ posted to rec.crafts.winemaking regarding pH meters in
general. It is geared toward winemaking, but in general terms it's
really more about selecting and maintaining the right one for your
needs. No one wants to buy the wrong one and have to replace it.

A popular pen style version with winemakers is the Hanna pHep 3 if a
resolution of 0.1 units is acceptable, the pHep 5 if a resolution of
0.01 is needed. (There are LOTS of manufacturers out there, Hanna is
by no means the only one I would suggest; the FAQ lists several
websites.)

If that accuracy is unneccesary, litmus paper is a much less costly
alternative.
Hope this helps,
Joe

It sure does help, thanks much Joe.

What's your favorite type/brand of buffer solution? Do you prefer
premixed liquid or the tablet/capsule type?
