It was stated as being within 3% of the reading. But the units of measure of the reading are themselves in percent.So I wrote the following to the manufacturer, asking if I had a reading of, say, 10% did that mean the range of error was 9.97 - 10.03% or 7 - 13%.This was their reply:The accuracy is ±(3% + 3 digits) as stated in the manual. To use your example, if the meter reads 10% then it is really between 7%-13%. The website will be updated accordingly. Thank you for bringing this to our attention and if there is anything else you have questions about, please feel free to contact us. **Q: Can I use this product to rule out a plumbing leak under my concrete bathroom floor. The outer bathroom wall is concrete & paint is bubbling.** A: It won't show thru the cement unless it is wet. Also is the wall an exterior wall & you could be getting moisture there. With the paint bubbling you do have a water problem from some where inside or out, but you could check with the tool on the inside in the wall real low next to the cement. It worked real well for my particular problem without tearing up the carpet to find my problem. Hope this helps. **Q: I have a wooden floor that is swelling little bit. I know I had a small water leak. Can this tool help me to check if there is moisture underneath?** A: ABSOLUTELY! This is just what you need, it tells you the exact moisture where the contacts touch the wood. There is a small button on the face right under the word GENERAL that allows you to pick wood or concrete. I use it on our Maple flooring in the summer to see where we are with water content. **Q: Will it measure moisture in drywall?** A: Yes. It has two features (1) Wood which I use on dry wall, wood, plastered walls, carpeting.. (2) Building material which I use on concrete floors, concrete blocks... I have found it works well on concrete and I can trace moisture in our basement floors which has helped to target where work needs to be done in outside grading. By the way I am a 78 year old woman and have had "fun" using this meter. Money well spent. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple and easy to use *by M***A on 6 April 2022* Easy to use with timber ### ⭐⭐⭐⭐⭐ Works well *by P***B on 21 October 2019* Works well and seems to give accurate readings ### ⭐⭐⭐⭐ A very good moisture meter if only ........ *by K***V on 13 April 2022* A very good moisture meter if only they put more substantial pins on as the tips bent first couple of hard wood samples tested, I wanted to give it five stars even though you get a spare set of pins. ## Frequently Bought Together - 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 - Klein Tools ET140 Pinless Moisture Meter for Non-Destructive Moisture Detection in Drywall, Wood, and Masonry; Detects up to 3/4-Inch Below Surface - General Tools PIN3 Replacement Pins for MMD4E, RHMG650 and RHMG700DL Silver --- ## 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.ae/products/52999205-general-tools-moisture-meter-pin-type-digital-lcd-mmd4e](https://www.desertcart.ae/products/52999205-general-tools-moisture-meter-pin-type-digital-lcd-mmd4e) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-03*
