Instead of guessing whether the wood you’re assembling (or painting) has the proper moisture content, why not find out for sure? Delmhorst’s BD-2100 Digital Moisture Meter can gauge moisture levels in wood from 6 percent to 40 percent. It can also take moisture readings in other materials, such as gypsum, concrete, and EIFS. The standard contact pins provide 5/16-inch penetration; various electrodes for deeper penetration are available as accessories. The BD-2100 is made in the U.S. and can be found online for $340.
