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

Works and preforms as expected!

We had seen a clear water stain but it was hard to remember whether or not it was there before. Since we thought it was fresh, we wanted a way to test that would not damage the wall. Picked up this item and within moments after opening the package were able to detect that the stain was fresh. As a result we were able to get repair work underway before the next rain. Awesome tool.

Id give this 5 Stars if it werent for quality control issues Klein needs to address. It took three meters before I finally got one that read zero when not reading anything. The first two always read 2-3 percent when turned on and/or not reading anything. I contacted Klein about them not zeroing out and they said they were defective. I assume its a calibration issue which can only be fixed at the factory. That said I love the meter but it was very frustrating to get one that worked correctly.

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.

User friendly and accurate.

For the first delivery received, the Digital Moisture Meter kept shorting out. I returned the items and received replacement (for all three items). For the second delivery, the Non-Contact Voltage Tester did not work. The GFCI Outlet Tester was fine. At least two of the three work now, so Ill hold on to them. I would recommend going with something of higher quality. If it happened to me with both shipments, theres no doubt that this is happening to a lot of people who purchased these items.

We have engineered hardwood floors in our kitchen that were flooded because of an ice maker valve leak behind the refrigerator. As a result, some of the planks started to buckle. We used several fans to dry out the leak and I used the moisture detector daily to check the moisture content of those planks. It was very easy to use with its three settings; Hardwood, softwood, and drywall, I was able to determine when the planks were dry and also the condition of the adjoining dry wall. The monitor will detect down the 3/4 and the display gives both the percentage of moisture and and an audible tone. It turns out all the water evaporated and the planks returned to original state. If it had not been for the detector, my wife would have spent thousands of dollars on ripping out the floor and replacing it with some other type of flooring.

Got this because we had moisture in some outer walls where sheathing bowed out. After sealing things I wanted to make sure it was sealed and see if some other hidden areas need work but it seemed like it either reported a low moisture level or excessive moisture with nothing inbetween. Also little context on results. Seems like it is meant for stored lumber and drywall rather than in-place materials but hard to tell if its doing anything useful.

Great tool for the price!
