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 ### ⭐ Inaccurate readings. *by A***R on 20 November 2022* Use this on any surface and the readings will be high. Compared against a probe type its a mile out. Completely useless. ### ⭐⭐⭐⭐⭐ Value for money *by R***D on 11 April 2022* Came as expected no complications thank you ### ⭐⭐⭐⭐⭐ Review *by C***N on 18 November 2022* This is a great little moisture reader. I have tried other models and they give you some numbers and different modes for different types of material but what do you do with the numbers??? what is a "normal" reading? etc... I used this to detect possible leaks in the walls. Most moisture meters out there tend to specialize for measuring moisture in wood and various material. This one works really really well for regular dry wall! You drag it slowly along the wall near areas where you suspect there might be a leak. For my part, it discovered that while there was no pipe leak, there WAS a lot of wicking moisture from the grout in the shower to the backing drywall material (an old shower without a waterproof membrane). The meter was VERY clear. In most area, it would show 0% moisture. As I approached the shower, it gradually increased all the way to 100%... There is also a color scale indicator (from green (OK) to RED... bad/wet!). And once you pass a certain level of moisture, the meter will also beep! Like I said... NO AMBIGUITY with this device. It will tell you in simple terms: You are OK or HEY! There is excess moisture in this wall! Verdict: GET IT! Get it if you suspect moisture or water leak in a wall. At about 20% moisture, you may start having some mold in the wall. This meter is affordable... it's worth having one on hand! ## Frequently Bought Together - General Tools LCD Moisture Meter #MM8 - Leak and Humidity Detector - Pinless and Non-Invasive - General Tools MMD4E Digital Moisture Meter, Water Leak Detector, Moisture Tester, Pin Type, Backlit LCD Display With Audible and Visual High-Medium-Low Moisture Content Alerts, Grays - Etekcity Infrared Thermometer Laser Temperature Gun 774, Meat Food Candy Oven Thermometer for Griddle Accessories, Heat Gun for Cooking Refrigerator Tools, Yellow --- ## 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.co.uk/products/75454902-general-tools-pinless-lcd-moisture-meter-with-tricolor-bar-graph](https://www.desertcart.co.uk/products/75454902-general-tools-pinless-lcd-moisture-meter-with-tricolor-bar-graph) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-23*
