Review: easy to use and reduces guessing - ★★★★★ Excellent moisture meter — easy to use, accurate, and great for home protection This moisture meter is an outstanding tool for anyone who wants to protect their home, workspace, or renovation projects from hidden moisture problems. One of the things I appreciate most is how easy it is to use. The large 2-inch backlit LCD screen is clear and readable, and the 3-color LED bar graph gives quick visual feedback that makes checking surfaces fast and simple. The audible alert is also very helpful when scanning multiple areas. A huge advantage is the pinless design, which means it doesn’t scratch or damage walls, wood, or finished surfaces. That makes it especially useful for homeowners, contractors, and DIYers who want accurate readings without leaving marks behind. The deep-reading capability is another major plus, since it can detect moisture up to 3/4 inch below the surface. I also like that it works on a wide range of materials, including softwood, hardwood, drywall, wallboard, and masonry. It’s a great tool for spotting damp areas early before they turn into mold or more serious damage. Overall, this is a smart, reliable, and well-designed product that gives peace of mind and helps prevent costly repairs. Highly recommended!

## Questions & Answers

**Q: Does it sense moisture through a painted surface or just the moisture content of the paint?**
A: It senses moisture through a painted surface.

**Q: Can this be used on concrete and drywall?**
A: Yes, the device has four modes.  Wall, masonry, soft wood, hard wood.  Wall is drywall.

**Q: Can this be used to locate a leak behind drywall. The drywall is not showing wetness so the water is probably running down a stud or outside wall.**
A: This tool will measure the moisture content of any building material including wood and drywall. If the test indicates a high moisture content in just one spot, you could probably conclude that there was a leak at that point.

**Q: Will this unit work on a plywood sub floor, and hardwood flooring to verify the hardwood has properly aclimated for installation?**
A: In order to get accurate readings you will need to make sure the two prongs on the top make contact with the area you wish to measure for moisture.  The two prongs are pretty small and the tips are sharp.  I was able to obtain readings on wet drywall, plywood and ceramic floor tile. As long as contact was made with the points it worked for me and the price is reasonable.

This may not be the most precise sensor but it is accurate at being able to locate the source of a potential leak or at least tell you if there is an underlying problem. I like that it is non penetrating so it doesn't leave any damage to the walls or ceilings. I've successfully used it to help find water leaks/damage in drywall walls & ceilings (including textured) and also PLAM (laminate) countertops. It helped confirm that a section of counter was actually water damaged and not a fabrication error or other damage, which lead to thankfully finding the source of the leak.
