To ensure your wood flooring is at an ideal moisture content, you need to check the relative humidity of the installation site and compare that to the %MC of your wood materials. Here, using a thermo-hygrometer to check temperature and humidity can be invaluable.
Most likely, your installation will probably be in a zone with RH values between 40% and 45%. If the temperature of the building is between 75 and 85 degrees Fahrenheit, the equilibrium moisture content of your wood should be between 7% and 8%.
Moisture meters for wood flooring can be used to quickly and accurately determine the moisture content of the wood. In most cases, you’ll be able to determine if a piece of wood is dry enough to use within a matter of seconds. This means you can avoid having your wood pieces warp or crack over time which can happen if they’re too moist. You’ll also know before putting your wood flooring down, giving you a chance to check for small holes or cracks which might have otherwise gone unnoticed until it was much more difficult to fix.
