<DIV>My info is that wood moisture content meters are not good for the =
low
moisture contents commonly targeted in board drying. And the cheap =
hygrometers
commonly available have a best accuracy of about <U>+</U>5% relative =
humidity -
which translates to a moisture content accuracy of about <U>+</U>7% (I =
don't
think that is good enough).</DIV>
