Editor's Review: Moisture-Meter Survey

by Lon Schleining

review date: October 25, 2005

The most common problems caused by moisture in wood are finishes that don't stick, joinery that breaks apart, and boards that take on new and unwanted shapes after milling. The solution to all these problems is to use wood that has been dried to the right moisture content, between 8% and 12%. And the easiest way to determine moisture content is to use a moisture meter.

Moisture meters use either pins or an electromagnetic plate (pinless) to measure moisture. Some pin-style meters take deep readings with hammer probes; others take readings from 5/8 in. or less. Both styles leave marks. Pinless meters leave no marks but require the wood surface to be smooth; they detect moisture down to about 5/8 in. I looked at a dozen meters priced from $60 to $350 and was surprised to find that their overall accuracy is quite good.

The Delmhorst J-4 is easy to use: Just stick in the pins and push a button. I like the analog dial a great deal, and the instructions are easy to understand. It comes with a slide-rule-type temperature-correction tool. A hammer probe is an accessory.
