The measurement of wood moisture is seamless and easy. Now, as for how accurate the measurements are, I have no idea. A comparative test should be conducted.

Excellent small tool/meter that does its job perfectly. I bought it because I had moisture on an internal wall and it showed me that indeed the wall has moisture, but mainly the percentage of moisture that indicates the size of the problem. I was able to monitor what was happening during a few days after rain, etc., as well as identify the areas that have the biggest issue. Just follow the instructions in the manual. It measures both structural materials and wood, as well as ground moisture!
