General Tools MMD7NP Pinless, Non-Invasive, Non-Marring, Digital Moisture Meter, Water Leak Detector, Moisture Testerup To ¾" (19mm) Deep, Backlit LCD Screen, Visual/Audible Alarms

When sheetrock, plywood, and fiberglas (like tub surrounds or laminate flooring) are wet, the sound is extremely loud. This tool really saved my life when I looked at used RVs. As a result of removing wall panels, I found soaked insulation and moldy or rotted flooring in several of the wet units.

The set has been in my possession for almost a year, but I have not used it. As an experiment, I sopped the back of a piece of 5/8" drywall with water until it soaked into Despite the meter's best efforts, it was not detected on the "wall" setting it barely detected it on the "softwood" setting it detected it a little more at 1% on the "masonry" setting, and not at all on any of the other settings. Water would practically have to saturate through the gypsum to the outer surface in order to detect, which would be pointless by that time, as you would already be able to see the You need to avoid having the backside of your wall soaked with water and it causing a "green. " This will lead to Despite the fact that 5/8 is thick for wallboard, these penetration devices are designed to go through approximately 2 inches of wall. Can you please help me out? I don't think so. Water penetrated the paper after I scarred up the back of the paper so that it could be penetrated with help. The readings I got were 60 to 70 If that's the case, then 100%. Therefore, water running down the backside of the drywall will not register unless it can reach the inner layer of the paper backing. This is basically a wall full of water that is left to sit for a while.

There are tens of thousands of reviews on this product, but I don't know if it was discussed. This meter offered a consistent false elevated moisture reading at corners where it consistently gave me a false reading for plumbing leaks behind drywall, so I concluded that it is accurate in most areas, except at corners. As soon as I removed the drywall from a spot a couple of inches from a corner where the meter indicated there had been moisture (all bars lit and an alarm went off), I found the drywall and the stud below bone dry without a sign of moisture being present. When I placed the meter at other corners where there was no possibility of moisture, the readings were very high. As I moved the meter just an inch or two further from the corner, the readings dropped to almost zero. In the instructions, there is no reference to this, so be wary. If drywall moisture readings are high at a corner, anyone planning to demo might want to test multiple corners as well.

In fact, I think the drywall inside my bathroom has a different moisture content from that found inside my room because it is painted in the same color as my room.

My opinion is that it works best on wood and concrete. It is even more accurate to work with bare surfaces. I am updating My eyes caught sight of this review as I scanned my reviews. In the months in which I have owned it, I have noticed some inaccuracies with the wood measuring software. There was a problem with moisture in my house! It is made by the same company, so I had to buy a pinned meter. One of these had a calibration in which you could check pin accuracy and pin placement. As you can see, the same wood did not have moisture problems. Comparing pinless models to pinned models, pinless technology does not perform similarly.

This is the Home Inspector that I use a few times a There was a hiccup after one year because the system started reporting concrete or brick as wet even though it was dry (but it seems to work fine for Having a moisture meter is an essential tool in my line of work. I shopped around at the competitive products, but found none that I found compelling, so I bought another and hope it will be more reliable than my first. This is a good buy.

I am an insurance adjuster and need a meter to determine where water is and is not. The way it is written does a superb Because of its limited ability and price, I rated it as a five star product. However, after a year of not constant daily use, but more regular daily use, the plugin stopped working. The Lost star can be found there. There is wear and tear on the pad on the back, which causes it to stop My phone turns on and I assumed the battery was bad, so I replaced it with a new battery. I still haven't solved the problem from that point of view. The second I bought was easy to use and cheap however, I would have liked that one to be durable for a longer period of time. As the old battery still has most of its charge left, I put it in the new meter, and now I have the extra I was so disappointed to find out that the battery lasted longer than the meter. To those who would use this instead of a professional assessment, I recommend working with a professional because their equipment is way more accurate and their drywall may read dry, but it's very likely that your wood studs are still wet, and this meter doesn't reveal There are a lot of benefits to using this utility, but remember it is only a reference tool, not a Although I will still rely on the app for what I need to know for my job, I will only rely on it daily. Almost all concrete and most thin flooring are wet with this meter, as well as most surfaces installed over concrete are wet or elevated. Not ideal, but I just use a reference point I know isn't damaged and use that as a baseline, then I look for elevated areas above that point.

it is hard to turn it off at its own. It is understandable that you would want to preserve battery life, but this is way I cannot slide the machine around the floor, as it turns off. If it is turned back on, the first setting, Walls, will be used. To click the >, I have to click The hard wood floor switch will return the floor to its original state. The problem is more than an annoyance if it occurs during testing a hard to reach area (such as under stairs).

A moisture meter was the tools I wanted to use when I looked at sailboats for potential purchases to check the level of moisture in the fiberglass deck materials. On the 'Wall' setting, it was able to give clear indications of areas with higher moisture content by giving very clear readings. In terms of readings for the boat I purchased, it was much more accurate than the much more expensive meter the surveyor used.
