It is impossible to tell how much moisture is in a piece of wood without using a moisture meter. These hi tech devices can tell how much water is inside a piece of wood with a quick scan. This is important while shopping for lumber and when looking for damage after a basement flood.
Wood that is high in moisture content is not good to use in home construction projects. If your wood moisture meter is showing high moisture content in a piece of basement wood after a flood it should be replaced as soon as possible. Wood that is high in water content is more likely to mold and can even cause structural problems in load bearing wood. The first step in preventing mold is finding it using a laser moisture meter to test each piece of wood.
In this article we reviewed the 5 best wood moisture meters of 2021 to find the best pick for your home. At the end of this article you will know how to pick the best meter for your basement and how to use it.

Picking the right moisture meter can be tough, there are many similar models with comparable features and functionality. We put together a buyers guide with all the information you need to know in order to pick the right model. We recommend picking a moisture meter based on the factors.
The most important variable for many homeowners that are shopping on a budget is the price. More expensive models may be more accurate but if you are only using it a few times per year it might make sense to sacrifice accuracy and go with a cheaper model. On the other hand if you are a professional carpenter or mold remediation specialists it might makes sense to invest in a more expensive sensor.
There are two primary methods of wood moisture detection – using small pins that leave tiny holes or EMF waves. Both methods produce accurate readings readings but many homeowners prefer pinless moisture meters because they do not damage wood or drywall. Pin-type meters may give more accurate moisture level reading but they also leave small holes on the wood you are testing which can be undesirable for some projects.
The power source is something that many people don’t consider when shopping but is surprisingly important in some cases. If you are a homeowner that plans on using the sensor every few months it might not be important since it can easily be recharged but if you are a contractor working on the job sit you will need a battery powered model.
Like many other tools – you get what you pay for when it comes to wood moisture meters. The best moisture meters are also the most expensive but they also have easy to read backlit LCD displays and are accurate deep into wood.
How to Use a Moister Meter
Each moisture meter is a little different. Most work by pressing pins or EMF sensors onto the wood, then holding the test button. After a few seconds the display will show the moisture content.
How Accurate Are Moisture Meters
Most moisture meters are accurate within a few percentage points. More expensive models can detect water in other materials like concrete, brick and drywall which offers additional advantage when looking for leaks.
