10 Best Moisture Meters for Wood – Reviews

1. Wagner Meters Orion 910 Wood Moisture Meter – Top Pick

Wagner Meters Orion 910

The Wagner Orion 910 is a great choice for anyone who wants the most accurate readings on the market. This model’s design hasn’t changed in years, and it’s a good example of not fixing a tool that works. It is a contactless moisture meter, which means it can detect a wood’s moisture content without inserting pins into the wood. Instead, lay the meter on the wood and let it go to work. It’s an extremely precise meter, measuring moisture content in .1% increments, which blows away the competition. It also works faster than a pin meter, which saves you a lot of time in the long run.

It can also be programmed to work with all kinds of woods, so if you’re working with more exotic stock, you’re covered. It also scans down .75-inches, which means that it goes deeper than most pin meters, meaning you get a more accurate representation of the moisture content at the center of the wood. The design is hard to learn to use. But, it’s the most accurate and one of the fastest meters on the market, so once you learn how it works, it’s a fantastic deal.

Pros
  • Contactless
  • Faster than pin meters
  • Works with all woods
  • Deep measurements
Cons
  • Ease of use

2. Lignomat Mini-Ligno E/D Wood Moisture Meter – The Runner-Up

Lignomat Mini-Ligno E/D

The Lignomat Mini-Ligno E/D is the best of the pin moisture meters on our list. While it doesn’t quite live up to the Wagner pinless meter in first place, it costs about a quarter of what you’ll end up paying for that meter, so this model is a good choice if you’re looking for a deal. It features a wider measurement range than the previous moisture meter, as this model can measure from 6% to 45% moisture content. It also measures in increments of .1%, so it is very accurate.

It is a pin meter, so you have to insert pins into the wood to get a reading. This meter comes with 3/16” and 7/16” pins, so you can adjust to deal with different thicknesses. It’s also very easy to operate as it only comes with two settings. Unfortunately, those two settings only apply to domestic, American woods, so if you’re looking to measure something exotic, you’re out of luck. While the ultimate downside to pin meters is that they leave little holes behind after measurement, but they come cheaper than the competition. Overall, this model is the best pin meter, and Americans get especially great value out of this buy.

Pros
  • Wide measurement range
  • 3/16” or 7/16” measurement depth
  • Easy to operate
  • Price
Cons
  • Only domestic species

3. General Tools MMD4E Moisture-Meter for Wood – Best for the Money

General Tools MMD4E

The General Tools MMD4E pin moisture meter is a great choice for someone who needs ballpark readings but also wants a great deal. You can get this model for about a quarter of the price of the second model on our list, which means that you’re not going got be out an arm and a leg when you purchase this model. One of the best things about this is that it doesn’t just work with wood. It comes with a drywall measuring function and can also be used to measure the moisture in subflooring, which is a feature that you won’t find in other moisture meters.

It also comes with a bright, easy-to-read display that most people love. The one real problem with this model is that it’s not terribly accurate. The manufacturer lists the accuracy as within ±3%. That good enough for knowing if there’s too much water in your walls, but it’s not accurate enough for drying wood. Installing wood flooring that tested as 10% water, but was 13% water would result in disaster, as it would crack and split as it dried. Overall, this is the best overall model, especially if you don’t need extreme accuracy.

Pros
  • Price
  • Works with drywall and subflooring
  • Easy to read display
Cons
  • Accuracy is questionable

4. Sam-Pro Tools Dual Moisture Meter

Sam-Pro Tools Dual Moisture Meter

The Sam-Pro Tools Dual Moisture Meter is a good choice for people who need a monster measurement range. It can measure between 0% and 70% moisture, which is massive relative to other moisture meters. It can also measure the moisture content of just about any kind of wood, fiberboards, particle boards, and even concrete. That makes it one of the most versatile moisture meters on the market, and one that’s great if you’re constantly testing different kinds of materials. It also measures temperature, which is good for a lot of tasks that involve drying.

It does have variable accuracy across its range, varying ±1% under 30%, which scales up to ±3% at 60%-70%. That’s not the most accurate meter on the market, but it’s the most accurate where it needs to be the most accurate, and that’s at the lower range. It does have an annoying safety cap that keeps the probes safe, but is a pain to remove, and can be frustrating. Overall, this isn’t the most accurate meter, which sinks it on our list, but it’s still worth checking out for its versatility.

Pros
  • Backlit LCD screen
  • Measures 4 material groups
  • Wide measurement range
Cons
  • Variable accuracy
  • Annoying safety cap

5. Moisture Meter, Digital Damp Meter Detector

TACKLIFE MWM03

With an excellent accuracy range of 2 percent, the TACKLIFE digital moisture meter provides reliable measurements in up to seven different types of wood and building materials. The backlit LCD helps you see your measurements in the dark, and the built-in flashlight adds another level of convenience.

A dedicated button switches between temperature units, a nice feature that we hoped to see on more devices. For the price, you can’t ask for a whole lot more from your moisture meter. That said, we would have liked to see an audible alert as well as a greater range of materials that can be tested. Despite this, we think it’s a very competent meter overall.

Pros
  • unit button
  • Backlit LCD
  • Flashlight built-in
Cons
  • No sound alert
  • Only tests seven types of wood and building material

6. SAM-PRO Dual Moisture Meter

Breathe Essential

Priced a bit higher than many similar competitors, the SAM-PRO dual moisture meter offers some great flexibility with the ability to read humidity in over 100 materials. The built-in air temperature sensor is also a nice added convenience.

Although several nice features are packed into the SAM-PRO, we still didn’t think it lived up to its price tag. We got some spotty readings, occasionally even getting no reading, though it did work most of the time. Testing it against our other meters, it was mostly accurate but not exact. This is a common problem experienced with many of the humidity meters we tested, but it still prevents this one from reaching a higher position on this list.

Pros
  • Reads over 100 materials
  • Backlit LCD
  • Includes air temp sensor
Cons
  • Expensive
  • Inaccurate readings
  • Sometimes doesn’t read at all

7. Pinless Wood Moisture Meter, Dr.meter Upgraded

Drmeter

The first thing that drew us to the Dr.meter pinless wood moisture meter was the pinless operation. We love the idea of getting a moisture reading without having to put holes in what we’re measuring. Unfortunately, it wasn’t fully accurate when compared to other meters. Although it’s advertised as having a 0.5 percent accuracy range, that wasn’t what we experienced. For the premium price, we were hoping this unit would function as expected.

What bothered us most with this meter was that it’s a bit of a hassle to use. This is mainly because it needs to be calibrated every time you power it on. Calibration only takes a moment, but it is an annoying step that always stands in the way of getting a reading.

Pros
  • Pinless readings
Cons
  • Premium price
  • Requires calibration before each use
  • Not accurate in our testing

8. Calculated Industries 7445 AccuMASTER Duo Pro Pin & Pinless Moisture Meter

Calculated Industries 7445

For such a high price, we had pretty high expectations for the AccuMASTER Duo Pro moisture meter. We were left a bit disappointed though. Having the ability to measure with or without pins is a great convenience that we appreciate, but this unit just doesn’t implement it as well as we’d like. The pins actually broke quite easily. Worse yet, the plastic around the pins showed signs of cracking as well. The real downfall though was that it wasn’t accurate enough to trust. We could have overlooked the high price if we got accurate readings every time we used it.

Pros
  • Pinned and pinless readings
  • Backlit LCD
Cons
  • Expensive
  • Not accurate
  • Pins break easily
  • Plastic around pins starting to crack

9. Wood Moisture Meter, Dr.meter Digital Portable Firewood Wall Paper Water Moisture Tester

Drmeter MD812

Though it’s priced very low, this digital wood moisture meter comes from the reputable brand Dr.meter, so we had high hopes for it. It didn’t quite live up to those hopes though. To start, the measuring range is too small, spanning only from 5 to 40 percent. This is a much smaller range than other models from competing brands, even at the same price point. Also, the pins need to be inserted deep into the wood you’re measuring if you want a good reading. Luckily, spare pins are included since this will make broken pins more likely.

Even at this price, most meters include a backlit LCD screen, but the Dr.meter does not. This makes the screen very difficult to see in low light conditions. Overall, we were disappointed in the Dr.meter, though it did provide accurate readings, something that many other models we tested did not.

Pros
  • Affordable
  • Includes spare pins
Cons
  • Small measuring range
  • LCD is not backlit
  • Pins need to be inserted deep to work

10. General Tools MMH800 4-In-1 Combo Moisture Meter

General Tools MMH800

At first glance, we expected the 4-in-1 combo moisture meter from General Tools to be our favorite. As soon as you look at it, the dual LCD screens catch your attention. Too bad we discovered later on in a dark basement that they’re not backlit. We were also drawn to the ability to measure with or without pins. This was a great feature, and both did work well. The audible alarm was also a touch we appreciated.

Although it looks pretty sleek, this meter doesn’t feel solid when you hold it. Instead, it feels cheap and light. For the very high price it sells at, we hoped for a rugged and durable unit that feels like a dependable tool when you hold it. We also experienced some issues with zeroing where the meter didn’t want to zero out correctly. The problem never persisted though, it was just a minor annoyance.

Pros
  • Audible alarm
  • Two displays
  • Pinned or pinless
Cons
  • Very expensive
  • Feels cheap
  • Problems zeroing
  • Screens not backlit

Buyer’s Guide

We hope that our reviews have already given you some ideas about what you want out of your next moisture meter. If you still have no idea which model is right for you, go ahead and check out this buyer’s guide. We packed it full of good general information about moisture meters, so you can learn everything you need to look before you go to buy.

Pin vs Pinless

There are two kinds of moisture meters for wood. The first uses pins, which plunge into the wood to give you an idea of what the interior moisture is like. These models generally have the most accurate readings, but their best feature is that they cost far less than the alternative. However, the downside to these models is that you have to plunge the pins into the materials to get a reading.

That means you’re going to leave small holes, which you may not want to do. You’ll have to work around them, either cutting out the offending section or ensuring that it’s not visible on the outside of your project. If you’re drying wood in stages, you’ll have to measure it multiple times, and that means a lot of holes.

Pinless, or contactless, moisture meters measure while sitting on the surface of the wood. While it might seem like magic, the underlying science is well-understood, and you can count on the accuracy of these models. The big upside is that you don’t have to put holes in your wood. The downside is that these models tend to be far more expensive, but for many people, that tradeoff will be worth it.

Accuracy

Not all moisture meters are as accurate as others. Meters that are accurate to within .1% are the best ones available on the market and having that level of precision will leave you confident in the reading. Most people find that spending a bit more to get the most accurate readings is worth it, but that doesn’t mean it’s true for you.

The next best models are those that are accurate to within 1%. These will generally be reliable enough for most applications, though you don’t get the same peace of mind you get with the models accurate to .1%.

Anything over that level isn’t that accurate, and you might make bad decisions based on that information. If you want to do yourself a favor, don’t buy a model with more than 1% variance in accuracy in the range that you’re going to use.

Other features

While the above categories are generally more important, you should still evaluate the other features that come with a moisture meter to determine how good of a deal you’re getting. Most moisture meters work best with wood, but some also work with other kinds of materials, like sheetrock and concrete. This makes them far more versatile, and more versatile tools are worth more, even if they don’t cost more.

You should also keep an eye out for moisture meters that also measure the temperature, as that can be a useful thing to know if you’re drying something, or if you’re worried there’s a hot- or cold-water leak. You can tell better where the leak is by following the changes in temperature, which may be a better guide in that situation than a moisture reading alone.

Some moisture meters also include the ability to record measurements and store them for later reference, which can be convenient in a situation where it would be hard to pull out a pen and notebook. For instance, this could make your job a lot easier if you’re looking for leaks underneath a home where you don’t have your full range of motion.

Conclusion

The Wagner Orion 910 is our top choice for moisture meters, as it’s a contactless meter that works fast, measures deep, and works with all woods. The Lignomat Mini-Ligno E/D comes in second, but it’s the best pin model and has a wide measurement range, which makes it excellent value for the price. Best overall for the money is the General Tools MMD4E which comes with an easy-to-read screen and works with drywall and flooring. The Sam-Pro Tools Dual Moisture Meter can measure the widest range of materials and the widest moisture ranges, but its accuracy issues drop it to fourth on our list. The last entry is the General Tools MMH800, which in theory combines the best of the pin and pinless moisture meters but isn’t accurate enough to be worth the money.

We hope that our reviews and our buyer’s guides have helped you find the moisture meter for wood that is right for you. While it’s not always easy to shop online, we hope that we’ve given you the knowledge and confidence you need to make a great purchase.
