I just picked up a Rapitest PH meter from Home Depot and I'm suspicious
of it's accuracy. I stuck the probe in to a glass of Coke and got a
reading of 6.25 which is way to high, Coke has is supposed to have a PH
in the neighborhood of 3. DOes anyone have any experience with these
meters?

IMHE the cheap pH meters are worthless. The even-cheaper test papers
(that indicate by color changes) are far better.
