Wood has a high moisture-absorbing capacity. Raw wooden materials of various forms quickly absorb moisture from the atmosphere in humid regions and swell up. It makes the wood damp and decreases its durability and strength. That’s why carpenters and wood makers use wood moisture meters to get accurate moisture content and other data.

Best Budget Meter
This digital moisture meter provides accurate readings with minimal deviation from the original value. Its LCD screen has a backlit display which helps in viewing the large digits. In addition, the meter is reinforced with three LEDs and pre-set tones for alerting you about the low, medium, and high moisture content levels. Due to the robust stainless pins, you can insert the device into both hardwood and softwood to get the readings instantly.
The output data varies from the actual results by a few decimal places when it comes to digital instruments. Even though the difference is minute, it still matters while working with sensitive test subjects like wood. That’s why having this digital moisture meter is more feasible. It will help measure the moisture content in wooden materials between a range of 5 to 50% maximum.
Pros
- It has a cap that acts as a calibration checker
- Will help in preventing mold growth in woods
- Makes different noises based on low, medium, and high moisture content
Cons
- No extra facility is available in the meter
Best for Firewood
There are several species of wood that are categorized into different groups according to biological taxonomy. Having this moisture content meter will help you to test 50 different wood species belonging to four different groups. You can select the group by pressing the “mode” button of the meter. In addition, it also has a hold button that will help you record the data by freezing the meter.
Its electrode pins are very sensitive, which is why the scale range is between 0 and 99.9% with about +/-0.5% accuracy. Since it runs on batteries, the manufacturer has included the auto shut-off feature to conserve battery power. On top of everything, you can see a low battery indication on the screen, alerting you about battery replacement.
Pros
- Has a durable frame due to the use of ABS plastic
- Comes with a protective cap for the sensitive pins
- Can measure MC% of 50 different wood species
Cons
- No different scale ranges are calibrated in the meter
Also Consider
If you are looking for a wood moisture meter with optimal features, this is a great option to consider. Firstly, it has two measurement modes— pin and pinless mode. The former mode requires you to insert the electrode pins into the wood material whereas, in pinless mode, a sensor will scan the material and display the results. Hence, you can work on all types of woods, including the high-quality ones for which pin mode is unsuitable.
The meter’s scale range is 5 to 50% in the pin mode, while in the scanning mode, the range varies between 0 to 53%. Also, there are four modes for scanning hardwood, softwood, gypsum, and concrete. Thanks to its advanced alert system, you will know whether the wood is suitable for use or not once the moisture content reading crosses 17%. It can even display humidity and temperature readings for better knowledge about the wood’s condition.
Pros
- Can measure temperature up to 40 degrees
- Has a very low error range for MC% in both modes
- Reading data can be frozen with the hold function
Cons
- Might be a little difficult to handle for beginners

Buyer's Guide to Finding the Best Wood Moisture Meter
Using a calibrated wood moisture meter, you can know the approximate moisture content in the workpiece, with very little accuracy deviations. Since you cannot use damp wood to build something, it’s better to check its usability and strength. This way, you can construct a strong furniture unit using wood pieces with less moisture content and no mold growth or dampness.
However, selecting the best MC% meter for woods is not everyone’s forte. With so many products available in the market, you can easily get bewildered seeing them. Moreover, an MC% tester is a sensitive instrument due to which you need to get your hands on the best product. To help you hunt for the most appropriate wood moisture meter, we have explained a few factors to help you find the best wood moisture meter.
What Are the Different Types of Wood Moisture Meters on the Market?
There are mainly two types of wood moisture meters that carpenters and woodworkers mostly use. These are:
Pin wood moisture testers
In these moisture meters, you will find two electrode pins with sharp tips present at the top of the device. You need to insert them into the workpiece and hold the device until readings are generated on the LCD screen of the wood moisture meter. As a result, these meters are more accurate, and the error percentage range is also less. However, you cannot use them while working on costly woods because the pins will leave holes.
Pinless wood moisture meters
From the name itself, you can understand that no pins are there in the wood moisture meters. Rather, a sensor is included in the instrument, which scans the material handling and displays the results. However, the results displayed are less accurate because they do not directly contact the wood material. Also, the error percentage is high, so they are used only for expensive wooden pieces.

Key Factors To Consider When Buying the Best Wood Moisture Meter
Scale range
Firstly, you need to check the scale range of the wood moisture meter. It’s better to get a huge range like 5 to 50% or 0 to 90%. The higher the scale range, the better will be the results. Also, you will be able to check different wood species belonging to different goods.
Error percentage
One of the most important factors that you should consider when buying a wood moisture meter is the error percentage. It defines the maximum error that may be present in the displayed MC%. So, for example, if the product you are buying has an error range of +/-2%, it means that the actual result varies from the displayed readings by 2%.
Accuracy
Just like the error percentage, every wood moisture meter has a certain range of accuracy. In this case, you will need a product with a 0 to 1% accuracy range to ensure that the readings are the closest to that of the original MC%.
What Are the Various Benefits of a Wood Moisture Meter?
To use the moisture meters in the best way, you should know what they can bring to the table. In the below section, we have discussed some of the major benefits that you can find in standard MC% moisture meters.
1. You can use the lock or hold button to freeze the reading at any time to record the instantaneous values.
2. You can either change the test material option or set a particular wood category with the mode button.
3. If your moisture content meter has an auto-switch function, it will help turn off the power when the device is not used for a certain time limit.
4. The pins can be replaced in meters once their tips become blunt, and you can’t insert them anymore into the workpiece.
Precautionary Steps To Remember While Handling Moisture Meters
- It would be best to make sure that the pressure applied on the pins of the wood moisture meter while inserting them into the wood piece is not excessive.
- If you use a pinless moisture meter, do not move your hands too much over the test material.
- It’s better not to use the moisture-checking meter with wet hands as water might damage the instrument.
- You need to set the testing modes before inserting the pins into the wood material or scanning one.
- It would help to keep the pin moisture meter covered with the safety cap so that the pins are safe from damage.
Common Moisture Meter Questions
Should I get a pinless moisture meter for wood?
If you are working with costly wooden material, using the non-destructive or pinless moisture meter will be better. This is because there will be no marking on the workpiece, maintaining its beauty and smooth surface structure. However, since pinless meters use scanning sensors for testing MC%, they have less accuracy than the pin moisture meters.
Won’t the pins break if I exert too much pressure while inserting them into the wood?
Usually, the pins of the wood moisture meter don’t snap or break even when high pressure is applied on them to insert them properly into the wood. However, if the pins are made from less durable and weak material, they won't withstand the pressure, and hence, they will break.
What is the maximum moisture percentage which makes the wood suitable for use?
In most hardwood and softwood types, the maximum amount of moisture that will make the workpiece still usable is around 17% to 22%. However, the range can increase based on the species of wood you are testing.
