Take quick moisture measurements from a variety of building materials using either the pin or pinless (non-invasive) method with the Extech MO55A. This easy-to-use moisture meter features a high-contrast color LCD with backlight for clear visibility in any environment. It uses intuitive display icons to indicate moisture levels and provides an audible alert that speeds up as moisture increases. Ideal for building restoration projects and applications where detecting moisture on floors, tiles, and under carpets is critical, the MO55A is also essential for analyzing the after-effects of water leakage behind walls and in ceilings.
