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 ### ⭐ غير عملي عندما اضعه على اي جدار في الحمام يعطي نفس النتيجة ولايوضح اين مكان التسرب *by A***D on 21 December 2020* طلبت هذا المنتج لكشف تسرب المياه ولكن لم استفد منه لهذا الغرض وكان عندي تسرب في احد الحمامات وحاولت بهذا الجهاز كشف موقع التسرب ولكن بدون نتيجة ### ⭐⭐⭐⭐⭐ 🤩🤩🤩🤩 *by A***F on 16 May 2025* Awesome ### ⭐⭐⭐⭐⭐ Easy to use right out of the box *by P***H on 18 January 2021* My laundry room flooded and I'm replacing the flooring. The moisture is in the sub flooring - along with the existing flooring. The floor company told me to buy a moisture reader to monitor the sub floor, because they cant install replacement/new flooring until the reading is less than 5%. When I first got this reader it was over 50% on the sub floor, so I have been using heaters and fans. Now it is down to 25% - but the best thing is... I know nothing about flooring or moisture or how to use moisture readers, but this is super intuitive and easy to use. > Just hit one button to tell it what material it is "wall, hardwood, softwood", etc. then it's super easy - just lay the reader where you want it to read and it does the rest. > Seems very accurate. If i test, then re-test again, readings stay consistent. > Would be easy to locate a leak. You really do just run it over surfaces and it will change in real time. I personally dont have an active leak, but this is accurate and can pin point areas that are more moist than others. > In the video - the sub floor is less moist than the flooring that was soaked and is still installed. You can see how it detects different moisture levels in different areas. Very nice way to monitor as moisture levels go down. > OVERALL - so happy I went with this model, even though I was comparing it with a couple others that were a little cheaper. This one works VERY VERY well.. that's all that is important when your in a situation where you need one of these. If you buy a cheaper one, that may not be as accurate - you will be kicking yourself later when your entire project is up in the air and your going to spend that extra $10 at Starbucks because your stressed out and need coffee :) ## 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.pl/products/253739927-digital-moisture-meter-mmd7np-humidity-sensor-pinless-and-non-invasive](https://www.desertcart.pl/products/253739927-digital-moisture-meter-mmd7np-humidity-sensor-pinless-and-non-invasive) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-09-05*
