Rated 4.3 out of 5 by 12 reviewers.
Rated 4.0 out of 5.0 by Simple Effective Moisture Meter OVERALL: Simple. Auto off on putting cover on is nice. LED is easy to read in most lights, back-lit would be nice. Reasonable accurate in my tests of wood moisture levels. FUNCTIONALITY: Just environmental moisture and wood, nothing fancy. Two pins must be stuck into surface to read, so may not be ideal for every application, but it works it you are willing. BODY: Very solid. I have a couple Extech tools, and have been happy with them, this one seems no exception. Fairly ergonomic and top stays on well, requiring a little pressure to sides to remove. September 9, 2014
Rated 5.0 out of 5.0 by Very Accurate and Easy to Use Moisture Meter I recently obtained the Extech Moisture Meter (Model M0210) for use around the house. I was intrigued by this device after seeing contractors from the insurance company using it to characterize water damage to my flooring and sheetrock walls. It's compact and very simple to use, and provides an accurate moisture reading in wood and other porous materials. In addition to tracking water damage, it’s great for checking the moisture content of firewood. The Extech Moisture Meter comes equipped with the batteries already installed. Removing the cap exposes the probes and turns on the device. The cap also includes a battery check and measurement verification tester to insure the meter is working properly. If the cap is left off, it automatically shuts off after 15 minutes to conserve battery life. The meter really needs a carrying case so the extra probes are not lost. Other than that, I am very satisfied with the product. It’s a must-have tool for remediation contractors and insurance adjusters needing to estimate water damage. October 1, 2014
Rated 1.0 out of 5.0 by Wish it worked like the first one. Stay away unless you have time to keep exchanging this item. The first one I bought worked great for about 3 months and then stopped working. so I bought another one and that one didn't work, I exchanged it and the next one did the same thing. I ended up with 4 non working meters since the store I was getting them doesn't sell them anymore and don't know if they'll be restocked again. Long story short, I wouldn't recommend this product to anyone I know but you may get lucky and get 1 that "might" work. October 29, 2015
Rated 5.0 out of 5.0 by Great tool for finding moisture in walls I had the opportunity to evaluate this handy tool. I have been using it to locate moist areas behind walls without the need to tear anything apart during home inspections. It works on many materials. The LCD and bar graph display is quite nice. It has a nice belt clip and is easy to find ( orange and green) when you set it down. It comes with several replaceable pin probes. If your proud of a job done right then be 100% sure future will not hold moisture problems that could have been avoided had you used this tool September 10, 2014
Rated 4.0 out of 5.0 by Simple to use and handy to check if you have moisture issue I got this to check if wood was dry enough before trying to make something from it. It does give you the moisture content and I have to assume it's correct. I don't have anything to compare it too. It's easy to use, just take off the cap and it turns on, it's a nice feature. Then just press the tips into a piece of wood and it gives a reading. In the cap there is a couple of test points one for checking the calibration and one to check the battery. It also comes with a few extra tips, I guess they wear out. If I get the chance I will check to see if its readings match that of other moisture meters. I also have used to the check if there is any moisture issues in the lower level of my home by checking the moisture reading in the drywall of the rooms I am doing some work on to see if I problems before moving on to finishing the space off.

Rated 4.0 out of 5.0 by Don't loose the cap. This meter will check both wood and building material. So it is handy for checking lumber in the wood shop, as well as checking thing like drywall for water damage. I like that the cap protects the probes, and the ease of use. As far as I can tell, it is accurate. (I don't have another one to compare the reading with.) The down side is that if you loose the cap, you can no longer turn the unit off. The meter automatically turns off when you remove the cap. The cap also contains contacts and circuitry that lets you test the meter and batteries. This is an interesting feature. The meter features replaceable probes, and comes with extra probes. This is handy after you have done enough tests to dull the probes. It will be interesting to see how long they last when checking plaster. All in all, I am happy with the meter. It is easy to use, and has nice features. August 29, 2014
Rated 5.0 out of 5.0 by Fast and easy to use I was having moisture damage issues in one of my bathrooms but couldn't figure out what was old staining and what was new. This made short work of finding the moisture and saving me from having to cut and patch multiple holes in the drywall to find the leak. What a time saver! I was pleasantly surprised how many spare electrodes they put in the package, they should last my lifetime. August 26, 2014
Rated 5.0 out of 5.0 by Works well Works well to help identify potential moisture problems in your home or for checking the moisture content of wood before staining or painting. Can easily pay for itself by helping find problems before it's too late. Regularly check around windows and doors after a rain, under or around plumbing, etc to make sure everything that's supposed to be water tight still is. Detecting water problems before there are obvious signs can save you some big headaches. Take off the cap and the meter turns on. Place the probes on the material you want to check and read the moisture content. Put the cap back on and it turns off. Only other thing you need to do is slide the switch to either Wood or Building depending what you're checking. Wood obviously for checking moisture content of wood and Building for checking things like drywall. Display is a bar graph as well as a number. Comes with extra probes and the cap allows you to test calibration and check battery level. A belt clip keeps it secure on your belt or in your tool belt. October 1, 2014
