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

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.

I bought both this Klein and a TopTes moisture meter. They both give wildly inconsistent results. I suppose I should’ve pooled my money and bought one higher priced unit???

Initially it read 0.0% on all drywall. With several battery changes it started working and actually reading pretty accurately. It worked fine for a stretch and is now reading 0.0% again on all drywall. Have changed the battery multiple times hoping to bring it back with no luck. Because of this I would not recommend this product.

Would like not to select material since I only work with hardwoods but that’s my only slight crittisism.

Buy these if youre looking at houses to buy, save yourself headache down the road!

I’m trying to dry in a basement and have to make sure it stays under a certain moisture level. This unit is of high quality and is super easy to use.

I knew that I had some leaks on our travel trailer (whats new) but I did not feel like ripping it apart to find out where the water was. This tool confirmed my suspicions and told me where the water had soaked the insulation in my ceiling and walls. Since I have never used more expensive units I can not comment on the actual accuracy of this meter as compared those costing hundreds of dollars, however, for my DIY uses I think that this tool is easily worth its weight in gold. I can recommend it, especially for DIYers.

This unit helped me check several rooms in a new construction build for moisture. It took less than 15 minutes to do 4 rooms and the unit confirmed high moisture levels in one area I had suspected of water damage. Nice unit.

I was skeptical about this tool but we had professionals come in after we took our readings and their tools agreed with this one. Worth the cost. It does require pressing the tool on the surface so its not for checking dampness from a distance. Easy to use and read.

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.
