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

great product very rugged.

Used for measuring moisture in my subflooring plywood after my water heater went south. Wood measured off the chart. Took close to 2 weeks to dry out so I could lay new new laminate. Nice not to have to use pins, just lay on floor and scoot.

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

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. Im pretty sure the sensing plate on the bad unit was set too deep and couldnt 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 didnt 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.

Best money spent . A -PLUS !! very nice !!

Seems to be giving acurate readings. Came with dead battery which amazon replaced.

They made a very easy to use, reliable moisture meter. I am a hobby wood worker that needs to know moister content of varying thickness of hardwood and softwood and this worked great. The user interface is great. This is recommended over the “pin” type meters because it reads deeper and doesn’t make holes in the wood. Just be sure when using thinner boards to not stack them on other boards or materials as this can throw the reading off.

If you want to know what the moisture content of your wood is this is not the correct tool. Its accuracy is +-4% so if it reads 8% on the meter your wood could be as high as 12% or as low as 4% and thats a substantial change. It also changes its measurement if your hand is near it or not. Just testing this I saw a reading of 7.1% on construction lumber (seems crazy low) go up to 8.9% if I put my entire hand over it. Thats a measurement increase of 25.3%! If you has position has the potential to swing your reading by 25% this doesnt seem like its even remotely accurate.

Seems to work well. Haven’t compared it to other meters but definitely picks up moisture when I’d it’s present. As to the accuracy of the amount of moisture I can’t say.

Initially the item worked well assessing moisture content on a sailboat. Then it suddenly would only display an error message. This is clearly a cheap product that works well, most moisture meters run around $300-400, so assuming the next one works for a reasonable amount of time this will be a great value. We shall see.
