Nobody wants to have cupping or warping in their woodworking projects. One of the best ways to avoid these problems is to make sure that your material is at the correct moisture content when you use it. How to make that happen? A moisture meter.The new MMD7NP meter from General, $49.99, is pinless and, according to General, penetrates to a reading depth of 3/4″. The measuring mode can be switched between hardwood, softwood, drywall, and masonry. The range is 0-53% for softwoods and 0-35% for hardwoods.
While the price on this meter is low, it doesn’t offer the option of setting the readings for specific species, as some other meters do. Additionally, the accuracy, according to General, is +/- 4%, a big swing when you’re looking for readings in an 8% range. This meter, it seems, would be a good economical meter for getting a ballpark idea of moisture readings.
