Two different modes enable users to measure moisture in corner, hard to reach areas, narrow spaces and uneven surfaces. The spherical sensor measures the average moisture level up to a depth of 4-inches and its small contact area provides superb repeatability. ## Features - LEAK DETECTOR: Check for moisture on or below the surface of carpets, ceilings, and sub-floors. Our device has an auto power-off after 3, 5, or 10 minutes. It can help contractors, woodworkers, and homeowners on wood, drywall, and concrete projects. - TWO MEASUREMENT MODES: Features dual displays, including a jumbo LCD and a 40-dot tri-color LED bar graph. It offers 2 modes, pin (%WME) and pinless (REL), and it has a 9V battery, remote pin-type probe, manual/auto-calibration, and a hold function. - DEEP SENSING: For an accurate read with pin mode, use the attached pins or the 46" cable with pins and insert it into the surface material. The pinless sensor on the back can detect water leaks up to 4" behind walls and ceramic tile. - REMOTE PROBE: Early prevention is vital when stopping mold formation.

I am a fiberglass and gelcoat repair expert, this is the very one I own.... the back flat part reads 3/4 inches deep, but the probe goes in four inches deep! the only "real one out there" technology has changed a lot in thirty years, I've been in the business of gelcoat colormatching as well as the glass work, guess what? it even comes with needle probes to run down wall leaks in sheetrock. This is awesome and the best, by far... better then the over a thousand dollar ones! Get it you'll love this thing and be armed with the best unit money can buy too! Good Luck they call me "Dr. Gelcoat" New Smyrna beach Fla... **Q: I recently had moisture on the floor on one end of my basement. Could this be used to detect if there is also moisture present behind the drywall, within the wall? (The drywall is plastered, painted, and seems to be backed with a layer of plastic.) Thank you!** A: Well! I decided to keep my MMD950 after some calibration problems. It needs to wander and end up stable at 0 to 2% if the calibration is successful. The instrument is reliable when used in a comparison mode. On sheetrock if no water is present it'll read 7 to 9 in the REL mode. If there's water it will jump to at least 17 and maybe even 99%. On roof leaks, I feel it will pick them up, dry days showing a low reading and rainy days jumping significantly. If I were you, I'd take REL reading at various points on the wall around the basement and see if they show dry in some places. Then, over above water pool, check and see if you get a higher reading. The book says the meter shows four inches deep. I have no experience to confirm that. Don't be afraid to open up the sheetrock to look behind it. You gotta know what's going on. **Q: will this work on bamboo flooring and concrete sub floors?** A: Should work on the bamboo flooring but not so good on concrete. Concrete always retains moisture so you will always will get a moisture reading no matter what **Q: Would this unit read to 0.1% up to 10% or more moisture? Wish to use it on a food product** A: Your use of the number 0.1% would indicate you're looking for a high level of accuracy. I figure the meter is good for two or three percent plus or minus. I use mine to detect roof leaks. Six to 10 is no leak and 18 or above is a leak. Of course, as stated in the meter description, it'll measure zero to 99%. May be I don't fully understand your question! ## Frequently Bought Together - General Tools Moisture Meter MMD950 - Humidity Sensor - Pin Type / Pinless Device - Spherical Sensor - AcuRite Humidity Meter Hygrometer and Indoor Digital Thermometer with Temperature Gauge and Humidity Gauge, Room Thermometer Comfort Scale, 3 x 2.5 Inches, White (01083M) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/1401475-general-tools-moisture-meter-mmd950-humidity-sensor-pin-type-pinless](https://www.desertcart.sn/products/1401475-general-tools-moisture-meter-mmd950-humidity-sensor-pin-type-pinless) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-04-29*
