Klein Tools 80023P Tool Set, Home Inspector Tool Kit with Digital Moisture Meter, Non-Contact Voltage Tester, GFCI Outlet Tester, 3-Piece

I bought this meter to help estimate damage while adjusting insurance claims. It seems to work well and is fairly accurate when compared with the ones that the mitigation contractors use. It is not as accurate as the kind that have needles that poke into the material, but it doesnt leave marks on the material.

I have 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 1x2 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.

I use it for my Handyman projects and have great accurate results.

I have a rental property and the water heater gave out, flooding the unit. Although we were able to clear it up quickly, I needed to know where the moisture was and this device was invaluable.

I purchased this due to minor flooding in my home during Hurricane Ida. Some areas in my house were wet and others were not. However, since i wasnt sure of some areas i figured Id give this a shot. It worked like a charm. It was on point and told me exactly where the moisture was an how much of it. It saved me time and money since i knew which walls had to be cut or not. Very easy to use as well.

Great tool!

We needed to check our inner walls for moisture, and this meter did the trick for us.

After a leak in our bathroom, I wanted to monitor the drying process. This meter did the job great and came up with similar readings to a professionally calibrated meter. Highly recommended!

Just retrieved this pin-less moisture meter sold by Klein because Klein usually has quality tools. But this meter did not work from the moment I powered it on and selected the settings as outlined in the instruction manual. It always reads OL regardless of the mode setting, supposedly indicating the the moisture detected is outside the meters measurement range. I tried it on wood, drywall and concrete (masonry) slab of known dryness. It simply did not work. I am sending it back to Amazon and will try another meter from one of the local big box stores. Disappointed in Klein Tools on this defected unit.
