They must also know the difference between the two recognized concrete test methods and the 2 types of hardwood moisture meters. Most pin-type moisture meters use a scale calibrated to wooden, however this doesn't imply that the meters can't be used to measure moisture in other substrates and materials. These forms of moisture meters may also be used forconcrete, drywall, ceiling tiles, painted surfaces and more.

While some moisture meters provide an analog scale, others learn %MC digitally.

The accuracy of the %MC readings, in addition to the suitable substrate scales, range per meter and may vary by brand and kind.
