Thanks for the pH reading, Franz. As for the electric probe, your advice
has come too late! I bought one of these at Christmas and I agree that
they're worthless. I tested it with water, vinegar, and soil that I knew
was acidic, but the needle never moved from neutral.

battery not included? :-)

Battery not required (hmm, I'd best double-check that). I exchanged it for
another one, but that was just the same.
