While I've had limited experience with the Hanna hand-held pH meters, my
experience has been pretty good. If you accept their limitations, they are
very nice because they are easy to use (should say easy to lose!). If you
try not to impose too much accuracy on them, you'll get useful information
out of them. You can look at their readings as an indicator of the range of
pH the sample is in, then decide whether it is too far out of the optimum
range or not. If it is, act on it. If not, live with it. I like Allan and
Shawnee's approaches. Check your meter reading against plant performance. If
the plants, or sprays, are doing fine, accept it. If not, tweak it.
