The electronic material moisture meter is used for non-destructive localization and assessment of moisture distributions in walls, floors, or ceilings. Leak detectors can quickly gain an overview of the severity and distribution of damage in the building during the site inspection. After measuring the moisture in the damaged area, users can compare the index value with the reference value they previously measured in an area unaffected by moisture damage. This allows for conclusions about which areas of the building are affected by moisture and to what extent.
