Calculated Industries 7440 AccuMASTER XT Digital Moisture Meter | Handheld |Pin Type | Backlit LCD Display | Detects Leaks, Damp and Moisture in Wood, Walls, Ceilings, Carpet and Firewood

I'm a licensed Master Service Plumber and have had lots of different moisture meters back in my early days they were a very expensive tool to own now the markets flooded with all sort Well in my opinion this little guy is the best bang for the buck it's small very accurate the tips to probe can be replaced but no idea where to get them but they do unscrew so far I'm good and have yet to break yet but they are metal and will push into wood or drywall no problem and just snap off like some pos units I have had I love the back lite screen its very nice and its has fractional measurement the best is the ringer bell noises it makes when it's in stuff that's wet I love it its the sound of money to me! It will make most home owners start to.make odd weird Cringe faces but that's what its meant to do find out if this leak in wall or whatever has spread more than it may show face value I use it weekly along with my Flir Thermal Camera to pinpoint leaks before I swiss cheese the walls or ceilings to discover of such a leak so if your in the trades and looking for one of these look no further its perfect and hey if you drop it off a 12 foot ladder been there done that but hey no big deal it's only 30 not 300 dollars so Its not like dropping my Flir Thermal camera ouch! Thate an expensive day then now I'm gonna make cringing faces lol And I was not paid or anything promised to make this review just bored waiting on my next customer to get home and will be using this little guy again its paid for itself a long time ago one bit of advise always keep an extra 9volt battery with your gear for it tho as that's when it will die on you when your trying to show the client and whalaa

This is my first moisture meter, so I have nothing to compare it to, but I'm very pleased with it. I use it for checking my firewood to see if it's ready to burn. It seems very well built. You have to push with a little force to get the prongs to go into the wood and I was a bit worried that those little pins might be fragile, but they are not. They are sturdy and the case seems to be up to the task as well. I've played around with it a bit - testing a piece of wood and then leaving it in the house for a while and everytime I test it again, the moisture level has gone down just as you would think it should. I like the fact that it will shut itself off if I forget to do it. One little surprise feature is the beeping that indicates moisture level. If the level is really low, the beeping is slow. Then as you go up in moisture, it beeps faster. The cutoff for burnable firewood is 20% and if the unit measures over 20% is beeps quite fast, sort of like It's saying, "This wood is not ready!". I should also mention that the readings I get are consistent with what I see when I burn the wood. If I measure a piece at say 18%, it lights right up and burns with no steaming or hissing. If I measure one at 22%, then there will be some of the steaming and hissing after I put it on the fire. It comes with a 9v battery and I was pleased to see that it was an alkaline battery, which should last for quite a while. It seems like most things that come with batteries come with the cheapest ones possible - this was a pleasant surprise. December, 2024 I stumbled on this review that I'd done back in 2017 when I first bought the meter. (I just recommended this product to a friend and looked up my order). I can report that it is still working after about 7 years of use! I replaced the battery one time so far. I heat with wood and cut 4 or 5 cords a year - I have used this meter 100's of times since I got it and it's still going strong.

Meter seems to work well. I tested some old ash at 10% and some Norway maple felled in spring at 22%. One star off for the cellophane-wrapped dead 9 volt battery that came with it. It couldn’t be easier to use

This was used at our Church - on the 18" masonry walls - that WERE full of water after a serious water leak problem... We've been using this to monitor the block wall water/ dampness - to know when the walls are FINALLY dry enough to be able to begin re-sealing the walls - and re-painting the walls... It's been (and STILL is) extremely helpful in monitoring this problem - luckily - we are NOW - FINALLY - able to begin our re-sealing and priming and re-painting of The Church basement walls. This is and was - exactly what we needed to monitor our water issue - without having to have a contractor repeatedly come onsite to let us know where things were at - that is a cost we didn't need to continue have ongoing - as we already had such HUGE expenses as a result of the initial water leak issue. It has saved us a lot of money - and now we're able to monitor OTHER areas if/ when maintenance feels it necessary. Great purchase - WE'RE not disappointed - you won't be either. :)

I don’t often write reviews, but this one deserves it. We’ve been having a very odd smell in our home office and it’s been driving me crazy. I suspected a mold problem under the window but couldn’t pinpoint it so I bought this to poke around and try to find the exact spot. Within minutes of unboxing this I had the moist areas behind the drywall identified and found my problem the next day. This saved me a lot of extra work because if it wasn’t for this I would have been cutting holes all over my wall and the problem was not even under the window as I suspected. This is very easy to use and it is extremely accurate. I’ve read complaints about the pins being damaged but they seem very sturdy to me, no problem piercing drywall multiple times. Extremely happy I found this.

Works well, but more for professionals that work with wood all the time. If one is building furniture or saves lumber for firewood, or other things where you need to know the moisture content, it's a great tool to have.

I use this regularly to check the moisture content in my firewood. Very easy to use. Numbers are easy to read, prongs are sharp enough to get into the "meat" of the wood. I compared the readings on this meter to other more expensive meters and it reads within %1 of them which is acceptable for my application. I liked it so much I bought another as a gift for a friend.

I would not say that it did not work, I would say that it gave me some indication of moisture. The amount of experts called in and I asked that they use this device. The seem to be fine to use for detections. Like I said, I can’t say I’m not a believer.

Stopped working in a weeks time. Amazon didnt pick the unit within return period.

Très efficace pour un lot d’application!

No prende el aparato y cargue la pila e igual no funciona sería bueno que los calen antes de venderlos

It's good but the beeper is so long and loud it leaves me no choice but to open it up and destroy the buzzer component :)
