I know all of you own a little pocket pH meter, right? If you don't
these are available for $50-60 from Fisher Scientific and many others and
are exceptionally handy. Be sure to get one that is accurate to 0.1 pH
unit. Good. Now that that's out of the way, be sure to get a hand-held
conductivity meter too, one that measures in the lowest ppm range (starts
at 0, preferably with a resolution of 1-2 ppm), typically available for
$50 or so. This will tell you if your water is pure enough for CP.

Most of the pH meters around the labs do pH and conductivity; you
should be able to get an all in one easily enough.
