I agree, the meters have to be calibrated, and to calibrate you have to buy
the solution they sell, as it is darn difficult to make your own salt
solution accurate without a chemist's lab to do it in. (So says my chemist
hubby). I suppose one could calibrate the meter by using the liquid test to
double check the reading? Course it wouldn't hurt to be able to double
check the liquid test either.

What a hobby you've chosen, huh? ;o) ~ jan
