The typical cheap moisture meter uses prongs to measure the moisture, the
inductive ones are fuzzy magic and they aren't very reliable unless you get a
very expensive one.
Flir has a new camera that works well and is only a couple hundred dollars, but
if you are only going to use it once it is kind of expensive.
I would say that the temperature gradient that Flir gives you is a better
indication of moisture than the inductive unit as three inductive unit can be
easily fooled by changes in material density.
