This is a handy tool to check for moisture in the walls. Seems to be accurate. I like it because it has no pins that would mark the wall.

I live in Florida, and it’s perfect for sliding across the wall, checking for minor roof leaks during storms.

The delivery was the best experience I have ever had. I ordered at 11 pm est and got it by 7 am est that morning. Delivered within 8 hours of ordering and I was really excited. The meter is easy to use and helped me detect problem areas right away

Going around outside and testing various pieces of wood on structures, fences reveals the importance of protecting wood with paint or stain to keep it from drawing moisture. This tool is so useful, I have used it at least a dozen times since I purchased it a few months ago.

I needed a moisture meter to evaluate moisture after a rental property flooded from heavy rains. The moisture meter has several settings that can be used for drywall, softwood, hardwood, and concrete. By using the meter, I was able to know what flooring and trim needed to be replaced.

This works great! Bought it because I smelled mold in the house and within minutes I discovered that we had a leak in the shower and it detected it through the tile floor. It also reads through hardwood floor and walls.

Seems to work fine (have to assume it is correct so checked 3 stars for accuracy) however, the battery included did not work. When installed there was a clicking noise when I pressed start. I put in a different battery and it turned on immediately. Easy to operate and to read.

This device works fine, but its application is quite limited. For detecting water leaks within your home (as intended in my case), a thermal camera offers significantly more precise leak location identification. While thermal cameras cost more, they effectively replace this device.

drywall repairs for a living so it’s nice to have something to make sure there is no more moisture before we close at the patches..

e a chronic rain water problem in one exterior wall, it originates from either around a clerestory window or where the porch meets the wall. While I waited for the next rain storm, I thought I would see if this moisture meter works. I took a 1×2 foot piece of sheet rock and squirted about a third of the paper backing with water – not too much just enough to dampen it. After about an hour, I ran the meter over the plaster side around the area that I knew was dry and got a reading of 0% moisture; no surprise there. But as I moved to the dampened area, I got readings from 19 to 25 % moisture. The next day, I checked the sheet rock with a thermal imager and it indicated dampness around the edges and a couple of faint,I assumed ,damp spots – there was absolutely no visible or tactile moisture on either surfaces. I ran the Klein meter around the same areas, and the moisture meter showed positive in those identical spots. I was quite impressed. So, my conclusion is your sheet rock walls should be around 0%; this meter will indicate even the slightest bit of residual moisture.

use was soaked – INSIDE!. I bought this because of a disaster. I had actually two contractors, because the first got fired half way through, who didn’t cover my roof for almost a whole month during down pours and snow. My house was literally raining inside! I showed the “project manager” whom I thought was the contractor how much water was running down my walls. This is the space in my living room between two windows. He said, “what does OL mean?” Really? “OVERLOAD”. It is overloaded with water! I just laid my hand on the wall and showed him all the water on my hand. Do you know what his response was? “It’s our of my scope of work”. This happened January/February of 2021. I am actually sitting here in paperwork up to the ceiling ready to go fight this head on to the lead people in charge of this program in Washington DC.. No lawyer or contractor will help. Long story and I can’t say much. But it is showing proof that my house is ruined. It is a very expensive home renovation loan.

. 3/29/2023 Update: Klein replaced my unit under warranty, but if course I had to pay the return shipping, whereas if I had tested it right away I could have returned it to Amazonfor free.The new meter seems consistent with my miniLigno pin meter. I’m pretty sure the sensing plate on the bad unit was set too deep and couldn’t make contact with the wood, and looking at the new one I can see the difference.Original review: Purchased in July 2022 and tested operability when received, i.e. I installed the battery, turned it on, cycled through the modes and pressed it against some kiln-dried lumber in my shop. I thought it seemed odd that the moisture was so low, but didn’t pursue it. Removed the battery and stored it in a shop drawer where I keep my instruments. Fast forward to January 2023, I got the meter out and checked some 2 year-old air-dryed walnut…meter indicated about 1.5% moisture, which is impossible. Measurements on other wood were all in the same realm of impossible.I have an inquiry submitted to Klein, but I see a lot of reviews with similar issue. I will update this review if/when I have something helpful to report.

5 stars because the price was great especially considering It’s made by Klein tools. I loveee my Klein tools, and I own a lot of them. Functionality & features are so easy and nothing confusing or unnecessary about it. Looks great. Seems consistent with the readings it gives ( testing the same area multiple times for instance, you’ll get the same reading, and some might say well duh..but sh!tty tools give likewise Consistency. I can’t tell you how accurate it is, because I only know What’s the tools reads to me, but this style of meter is supposed pretty darn accurate, and I have no reason to believe it’s not. I love the scale it shows, from green to yellow, orange and then red Which All have corresponding percentage values, when it hits red, it gives an audible beep alert. You can pause the reading I believe. I was surprised at how light it was, I usually like all my tools to feel solid and durable but it didn’t bother me. It’s made of strong plastic or nylon, and I’m sure it could handle being dropped and tossed around. Unfortunately I lost this tool over a year ago Probably in a crawlspace ( I’m an HVAC contractor and do lots of residential crawlspace work also). A friend gave me his Ryobi moisture meter, same non-probe style as the Klein. I loved the Klein much more, although They operate similarly. I am going to order another Klein right now, and that’s why im leaving a review right now, a year later. And if I lose this second one, I’ll be buying a third one. Good tool great price. 5 stars
