Features:

  • DETECT MOISTURE- Determine the moisture content of wood and other building materials (like drywall) or check water damaged areas to see if moisture is still present
  • FIRST STEP IN MOLD PREVENTION - By checking suspicious water stains with a moisture tester around the house, you can determine whether the area is wet (a perfect breeding ground for mold) or has long since dried
  • ACCURACY- Stick the stainless steel pins into the surface of what you are measuring in order to get a read-out. Overall measurement range of 5 to 50% for wood and 1.5 to 33% for building materials as well as low, medium and high moisture tones and colored green, yellow and red LED visual alerts
  • EASY TO READ AND USE- Large 0.3 in. (8mm) high digits in a backlit LCD display for quick and easy viewing plus a hold function to freeze a reading, auto power off and a low battery indicator
  • INCLUDES- Extra 0.3 in. (8mm) stainless steel pins, protective cap that doubles as a calibration checker and a “9V” battery
It worked great on the 'Wall" setting

I bought this moisture meter to check moisture levels in the fiberglass deck structures of sailboats I was looking at for potential purchase. It worked great on the 'Wall" setting, giving very clear readings and indications of areas with higher moisture content. It compared well with the surveyor's much pricier meter on readings for the boat I ended up buying.

Another recommendation for checking firewood.....

Based on prior reviews here I decided to get this for checking moisture content in firewood. I have no idea how accurate the measurement is, but it seems to be consistent and that's actually more important to me. After a bit of time getting familiar with what it is telling me, I now find that I can quickly tell which pieces of wood are ready to go into my wood stove. Now when I bring pieces inside I use this meter to stage the pieces on my drying rack so I already know which ones are going in next and so far it has worked just dandy.

Works very well and simple to use.

I don't know how deep this goes through painted drywall but I feel it only detects moisture directly on the surface. The reason I say this is that I don't believe my bathroom drywall, which is painted the same as my room, have the same moisture content inside the drywall. Works the best on wood and concrete in my opinion. Bare surfaces comes uo even more accurate.

Great item to have

After my house flooded (thanks to Harvey) I needed a reliable way to see if my studs and furniture was drying. This did the trick. When the studs were less than 9% moisture at 50% humidity I knew it was safe to hang the sheetrock back. It also helped me properly dry my furniture and showed which ones need more time in the dehumidifier room. Great instructions and very accurate.

Already paid for itself Used it to keep a contractor honest.

Bought this to check drywall at the in-law's house. There was a roof leak near their chimney that caused damage to the interior drywall. Called someone in to diagnose/repair the leak but before paying someone to fix the drywall we wanted to see if the leak was actually fixed. Bought this a few days before it rained for the first time since the repair and sure enough it found moisture in the damaged area again. Had them come back to check their work. Guy said it was residual moisture from the first time it leaked (from 2 months ago... sure, ok) but quickly backtracked after I showed him the photos of the 5% reading before it rained and +20% an hour after the rain started up again.

A must for anyone buying and RV

If your evaluating a house, RV or boat for water damage this thing is simply awesome. It is super sensitive to wetness behind sheetrock, plywood and fiberglas (like tub surrounds or even laminate flooring). I used it when looking at used RV's and it was a life saver. I had multiple wet units confirmed by the owners after removing wall panels to find soaked insulation and moldy or rotted flooring.

Great Value for Money - Works Perfectly for Firewood

I just learned about these things a few days ago and had to have one. As usual, you CANNOT GO WRONG with General Tools. A great device that is easy to use and perfect for my needs. We buy a LOT of firewood and now I won't have to worry about being (pardon the pun) burned by sellers who claim they sell seasoned wood. You just pop the cover off, push the probes into the wood, press the button, and there's your percentage of moisture! Easy to read large display, and a bargain price compared to others that don't work one bit better. Highly recommended.

As an insurance adjuster, I had to rely on vendors to give me moisture readings in water claims. Now, I have been able to use this meter several times already to determine moisture levels in wood and sheetrock and trace down leaks in homeowners claims. I can see how it would help anyone trying to chase a leak or to see if the moisture had been removed sufficiently to determine the damage was not going to get any better, i.e., buckle in floor was not going to go down any further, no matter how much more dry the engineered wood flooring got. In the attached photo, I'm using it to show my insurance company client that the water issue in the claimant's kitchen has not been fully remediated because the reading is well above 10%. This is an actual insurance file photo, made possible by the clear display of this product.

Great unit at a great price.

I was just looking for a cheaper moisture tester for my woodworking shop as I needed to check the moisture in some slabs I had cut a year or so ago, and let me tell you this exceeded my expectations I compared it to my grandfathers 80+ dollar unit and was always within .1 % of his meter. even if it is a cheaper unit it will get the job done and it works flawlessly, it is also nice that you get another set of pins to go along with it.

Excellent for checking firewood moisture

We've been having issues with our wood stove insert, and the Wife and I couldn't agree on the cause. At her insistence, I had already replaced the fire bricks, baffle board, fire blanket, cleaned the chimney ... and still no improvement. She just refused to believe me when I told her that the wood she ordered wasn't seasoned, but green. Ordered this ... stuck it into a few kiln dried logs and read 10% ... stuck it in our wood ... 30%!!!! Yep, green. Now if we order any wood I'll be poking it with this before they dump a single log off the truck. Oh - it powers on quickly, is easy to adjust between wood and building lumber. A reading takes less than a second once you poke the prongs into a log/board what have you. I like that it also includes a "calibration" tool in the cap - if it reads off by more than .1% it can be replaced under the 1 year warranty.
