Unfortunately, we had water damage and were measured with the device, the moisture in the wall. This also works very easy and - for private purposes - also quite accurate. The device displays the same points again and again to the same values. If you walk away from the wet spot on, of course, centimeter by centimeter decreases the displayed value. I can not quite understand why some recessions, which criticize precisely this behavior. For me, this device provides the desired information at a great price / performance ratio.
