Q. How accurate are digital moisture meters?

Answer

The most accurate moisture meters cost quite a bit of money but can provide readings to within 0.1 percent. Some less costly moisture meters are accurate to within 5%, providing an alternative to more expensive options. While this is still a respectable accuracy rating for the typical DIYer, those in need of a more accurate measurement should go to the more expensive devices. A moisture meter with an error rate of more than 5 percent is not worth the money. The results from a moisture meter are always presented as a percentage of moisture content (% MC). The typical range for a wood-specific moisture meter is between 5% (dry) to 40%. (saturated).
