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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***H on January 18, 2021* ### ⭐⭐⭐⭐⭐ Review *by S***A on February 23, 2026* ### ⭐⭐⭐⭐ Review *by A***J on February 5, 2019* ## Frequently Bought Together - General Tools Digital Moisture Meter MMD7NP - Humidity Sensor- Pinless and Non-Invasive - Mold Test Kit for Home - 12 Simple Detection Tests,Test HVAC System,Home Surfaces,& Indoor Air Quality Testing Kits,DIY Mold Detector at Home,Includes Detailed Mold Identification Guide,air Tester --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/7606462-general-tools-digital-moisture-meter-mmd7np-humidity-sensor-pinless-non](https://www.desertcart.in/products/7606462-general-tools-digital-moisture-meter-mmd7np-humidity-sensor-pinless-non) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-04*
