Moisture meters are among a woodworker’s best friends. This handy device measures the moisture content in wood, so you’re able to determine if it’s stable enough for you to use it. This way you’ll know if your lumber is too wet or dry to use for specific home improvement, building, or other woodworking projects! Or, you can use one to detect possible sources of moisture damage in your home, such as from leaks or floods.

Moisture meters come in two types: pin and pinless. A pin moisture meter measures the moisture content of wood by using two metal pins inserted into the wood. A pinless moisture meter uses a sensor pad placed flat against a board to measure, so there’s no insertion involved. We’ll discuss the pros and cons of each later on in this article.

What Is the Best Moisture Meter for Wood?
Of the choices listed above, we love the General Tools MMD7NP Moisture Meter, Pinless, Digital LCD with Tricolor Bar Graph. Although both pinless and pin meters have their merits, the MMD7NP meter offers the best of both features and value. This is a great first moisture meter if you haven’t purchased one before. It’s sturdy, accurate, and simple to use. Although you might need to test a few different areas to ensure a consistent reading, you won’t have to bore into the wood to do so.
How Do You Test for Moisture in Wood?
Testing for moisture in wood is quite simple. This happens in one of two ways, depending on the meter. With pin meters, all you do is insert the two prongs into the wood and wait for the meter to pick up a reading. Electricity flows between the two prongs – since water conducts better than wood, the meter determines the moisture content by measuring the current. Keep in mind that pin meters are sensitive to temperature variations within the wood, so pin meters always come with temperature correction charts.
Pinless meters use sensor plates to detect moisture in wood. Simply place the meter against the wood, and you’ll gather a reading. There must be enough contact between the surface and the sensor plates. It’s not advised to use pinless meters with warped or twisted wood since you won’t be able to gather accurate readings.

At What Moisture Content Does Wood Rot?
The moisture content at which wood rots depends on the species of tree and the humidity conditions in which the wood exists. But typically wood rots at a moisture content at 30% or more – this is the point at which fungal spores usually germinate. Spores can take a few days to become visible, but if you have dry wood that shows moisture content at 30% or above, you should consider drying it out.
What Is the Ideal Moisture Content of Wood?
The ideal moisture content for wood depends on the wood and its function. According to Wagner Meters, “the acceptable moisture level for wood objects used indoors is generally 6% to 8% for wood flooring, 6% to 9% furniture, and 9% to 14% for construction”.
How Much Moisture Should Hardwood Floors Have?
Hardwood floors should have approximately 6 – 8% moisture content, based on common recommendations.
How to Choose a Moisture Meter?
There are a few things to consider when purchasing a moisture meter for wood:
1) Pin versus pinless meter
The first thing to determine is which meter you’d prefer: a pin or a pinless meter. It depends on what you plan to use the meter for. If you buy surfaced wood which you wouldn’t like to poke holes in, you might consider a pinless model. There are no prongs to insert into the wood, just the sensor plates.
If you use rough lumber, extremely thick wood, or if you dry your own wood, consider a pin meter. You don’t have to have a smooth surface on which to place sensors. You can insert the pins almost anywhere along the length or width of the wood you’re testing.
2) Minimum sample size
Wood Moisture Meter General Tools Home Depot
Because pinless meters utilize sensor plates, consider the minimum sample size needed to obtain an accurate reading. It’s important to find a meter that isn’t too large for the wood that you’ll be testing.
3) Moisture content range
This is one of the most important considerations of any meter you purchase. If you’re just looking your run-of-the-mill meter to handle wood you purchase from your local hardware store or a lumberyard, you’ll be fine with a moisture content range of 7-20%. According to Popular Woodworking, it’s impossible to accurately moisture content past 30%. Some might purchase a meter with a higher moisture content range, but they are those who are usually drying their own wood and need to track how fast their wood is drying.
Wood Moisture Meter Review
Pricing is always a consideration when purchasing a meter. Some cheaper meters offer great value while still providing accurate and consistent readings and other features. Keep in mind, however, that their quality may not be as high as some other more expensive options. That’s not to say they are not worth purchasing.
Rather, consider how often you’ll use your moisture meter. It’s probably worth spending some more money on a good, solid meter with quality construction rather than something that might last you a year and not have all of the features you’d like. The meters in this list all fall within a reasonable budget. They each have their quirks, but all ultimately get the job done!
In conclusion, we’ve provided you with some information on moisture meters, reviewed some of our favorites, and offered some practical advice on what to think about when choosing a meter. Overall, it’s important to consider which meter you’d like to purchase, which moisture content range you’re looking for, which function you’ll use it for, and other factors.
