Moisture-Testing Products for Hardwood Floors
We asked several moisture meter manufacturers to discuss their latest products for measuring moisture in hardwood flooring. Their answers are below.
Grete Heimerdinger, Lignomat: “Most pinless meters are calibrated for a fixed material thickness of 3/4”. That means that accurate measurements can only be taken if the product is at least 3/4” thick.
“Lignomat’s dual-depth scanners measure 1/4” and 3/4” deep. Materials thinner than 3/4” can now be measured accurately with the 1/4” depth setting. This opens up new ways to use pinless meters.
“Many panel and floor products are only 5/8” thick, which does not work well for 3/4” depth. So when a floor of 5/8” planks is installed and you measure 3/4” deep, you cannot be sure that the subfloor or concrete underneath is not affecting the readings.
“You can find the moisture content of the thin hardwood top layer by using the corresponding species setting and 1/4” depth. Using those results, a setting can be found for the entire floor plank.
“All our moisture meters have a built-in calibration check and an internal automatic calibration adjustment. To show that the meters cables and electrodes are functioning properly, we sell calibration check blocks. In our manuals we also describe some easy pin and pinless check methods.
“Ligno-Scanners are convenient to use. The meters fit comfortably in your hand for measurements. The operation is simple with clearly marked push buttons. The large display shows moisture percentage and the settings for wood species and measuring depth.
“Lignomat’s unique measuring technology assures calibration accuracy, reliability, repeatability and dual-depth capability. Our scanners produce the same accurate moisture values today, tomorrow and in a year.”

Andrew Rynhart, Tramex: “We have launched a new pin-type meter with adjustment for more than 500 wood species and international calibration standards built in, as well as adjustment for temperature and automatic calibration. This PTM2.0 Professional Pin Type meter brings a new standard to pin meters.”
