Dr.meter Pinless Moisture Meters, Damp Meter for Walls with Backlit LCD Screen Non-Destructive Damp Meter 4 Mode for Wallboard, Wood, Masonry and Gypsum Boards

I bought this as I suspected a patch of dampness in the front porch and was attracted by its combination of use on softwood, hardwood, plasterboard and masonry. Once I installed the two included AAA batteries, removed the adhesive screen protector and switched on I found ease of use straightforward.It can be used in both a Scanning mode, whereby the rear of the meter is placed flat on a surface, or in Prod mode with the two metal probes exposed by flipping over a cover on the top and piercing the material you wish to measure. Bear in mind that the probes have to be pushed into the material so they will leave a couple of pinprick holes.Accuracy in Prod mode is plus or minus 2% while in Scanning mode (which measures to a depth of 20mm) is plus or minus 4%. An audible alarm sounds when Scanning reads >17% moisture in wood and 70% in masonry; and Prod reads >17%.I particularly like the Hold function, a button on the front which when pressed locks the reading for viewing and proved helpful when using in an enclosed space.A light, solid meter made in China that comes with a carry case that attaches to a waist belt. It’s backlit display is easy to read. Several YouTube videos of its use are available and it seems to feature in several Top 5 or Top 10 moisture meters. For the price I’ve found it to be good value.

Hand size tool with clear display and logical functions. Contained in its own protective case this is simple to use with clear display.I've nothing to base accuracy against but form a sample wood test it certainly detects variation.

used for damp in the walls and works perfectly, have the options of two sensors.

Not the most accurate device. But never are. Works well. I take a reading off a known dry wall for a base reading and can then compair to other readings. Does what I need with no issues at all.

Used for wood only, does the job

Does what it says. Only downside no real I details advising what the readings mean. Had to Google it

For: -Easy to use/read, big buttons and clear readouts.Pretty Accurate even when scanning.Excellent value.Non - cumbersome.ToughAgainst: -Pin cover swivels down and gets in the way but then caps are a nightmare.

Easy to use, excellent price

Lo compare con un equipo de alta gama y me dio medidas muy similares. Y buen precio

I had a leak in my house that damaged a 6x10 foot area of hardwood floor. This "Dr.meter" Wood Moisture Meter helped me pinpoint all the water under the floor, so I could tell how many boards to pull up. It's as easy to use as a stud-finder.I had a water remediation company come out, so I compared the Dr.meter to their $650 ProtiMeter SurveyMaster, and the results were essentially identical. The only shortcoming was that this only has a 0% - 35% reading for hardwood floors, versus the ProtiMeter's 0001-9999 relative readings; but it really didn't matter for real-life use. My undamaged hardwood floors measured 7% - 11% moisture content, and the slightly damp areas measured about 12% - 20%, and the wet moldy areas measured about 21% - 35%. I marked the bad areas with blue painter's tape, then started pulling up the flooring. Once I pulled the boards up, I could easily see the water staining on the sub-floor, which matched my tape marks, proving that the meter accurately found all the wet damaged areas!It worked equally well for drywall; the meter showed no water got into my walls. The water remediation company pulled out the drywall anyway, just in case, but it turns out that the meter was correct. If they had just pulled the bottom two inches of drywall, we could have easily patched it and covered the area with baseboard, but now I need a contractor to rebuild my walls, as well as the floor.Note that the pins only measure as far as you can press them into the wood (or sheetrock, or carpet), so if the top side of the wood is dry, the pins probably won't measure any moisture. The "pinless" (wireless) measurement is much better for finding hidden water between the floorboards and the subfloor (or drywall), but it can only read water down to about 0.8 inches, so it won't see really deep damage in studs or floor joists. There are more expensive detectors that can detect water up to 4 inches down.I discovered that even the industrial dehumidifiers and fans from the water remediation company can only dry surface moisture and carpets; once water gets underneath floorboards you really have no choice but to rip it up. Having a moisture meter really helps determine the extent of the damage before you start any demolition. Overall, an inexpensive but really handy tool that every homeowner should have!

Ik gebruik het om brandhout te controleren en het werkt zeer goed!

Fungerade bra på ved som jag skulle använda den till, bra med litet fodral som kan fästas på livremmen.

Lee muy bien ditintos tipos de superficies...Hormigón, madera, escayola, plástico.... perfecto para controlar la humedad de casco de barco
