In most cases, your installation will probably 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%.

If you’d prefer to go above and past, you may also give your purchasers a wooden ground moisture meter and practice them to take moisture readings every a number of months to keep moisture problems in verify and tackle issues earlier than they start.

Step 2: Set Your Meter
Be positive to acclimate the wooden to desired EMC of the interior setting earlier than you utilize it. The ASTM D4442 normal determines the accuracy of wooden moisture meters. This methodology makes use of the oven-dry methodology after which compares the outcomes to those obtained using a moisture meter. These various humidity levels of the surrounding air trigger wood to not solely gain or lose water moisture but to increase or shrink as nicely. As the humidity will increase, the MC increases, inflicting the wood to broaden. As the humidity decreases, the MC decreases, inflicting the wooden to shrink. When the wooden neither gains nor loses moisture, we say that the wooden has reached its equilibrium moisture content material .
