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 to measure the moisture content of wood, specifically hardwood. So, every time I use it, I turn it on, then hit the mode button a few times to get to hardwood, then I can measure what I want. (Unless I forget, in which case I usually notice that the number is very different from what I expected.)

Works very well easy to read as well as use.

If you are putting in wood flooring, or toung and groove walls, this tool is invaluable. Measure your wood and substrate. Know how much its going to shrink or expand. Gaps suck! Compression bows sucketh much more. This is the solution.

I do 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..

After a contractor poorly installed windows causing water damage, I bought this to check the rest of my home. I found two more areas that didnt show any visible water intrusion. Both new areas had dripping wet insulation. Who knows how long they would have continued to get wet if I hadnt made this $40 purchase. Now with every rain storm I run this along my windows frames. Super easy to use and read. Its accurate as it matched the waste restorations $1200 meter.

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.

bought it to use it on my TT, since there are some water intrusion issues... Its nice it doesnt make any holes in the material... Its accuracy?...I am not sure about it, since it seems to have a grey area after reaching 28% of humidity, it suddenly goes into overload (red LEDs lighting up)...would be better if it would be accurate till 100%

I had a plumbing leak behind my wall, and this thing was useless. On visibly wet sections, it gave me lower moisture readings than on sections that I later found to be unaffected by the leak (i.e., 3 feet above the leak location). I immediately returned it for a refund.

Update: numbers began fluctuating and I went to return the item but accidentally sent a $400 Wagner Orion meter instead. Klein accepted the item that wasnt theirs and refunded me $40. Now Im trying to deal with Amazon to get this sorted out and get my refund corrected for the other$360. I compared this meters results to the flir meter used by my remediation guy. The numbers were very close. Now I have a meter that will show me when the dehumidifiers and fans have done their jobs. A point off because it doesnt have as many material types that others do. Will come back if anything goes wrong.

Timely arrival and in perfect condition. Checked the accuracy against a friend’s borrowed meter and dead on. It’s a Klein, among the best out there at this price point. I’ve used other Klein meters for years and still have them in my toolbox. So durability is expected. If it meets your needs, Buy it.
