How We Chose the Best Wood Moisture Meters

We have covered general-purpose moisture meters before so here we wanted to focus specifically on those for testing moisture in wood. We wanted to provide options for everyone, from those checking their firewood to general contractors and furniture makers.

We researched over three dozen different moisture measuring devices to put together this curated list, looking at both pin and pinless moisture meters. We checked how accurate they were, the types of wood they were suitable for, how easy they were to use, and how much they cost.

We also contacted professionals for their input. Bob Berriz of remodeling experts Berriz Design Build, located in Arlington, Virginia, tells us, “Accuracy to within 2 percent is critical.” He added, “Mold and structural damage cost thousands to repair. An inexpensive meter, used properly, provides cheap insurance for any wood project.” Francisco Romero of Romero Hardwood Floors, based in Revere, Massachusetts, has similar advice: “I recommend a meter that provides readings within 1 to 2 percent accuracy and can measure at least 6 to 30 percent moisture content.” He also says that for contractors “data logging is key,” explaining that it tracks readings over time, verifying the wood has reached the target moisture before installation.

FAQs

So far we’ve looked at what we consider to be the overall best wood moisture meter. We’ve also offered some alternatives and discussed how we made our choices. In the following section, we answer some of the questions that often cropped up during our research.

Q. What percentage of moisture is acceptable on a wood meter?

It depends what you want to use the wood for. Firewood should ideally be below 20 percent moisture; wood used outdoors should be 10 to 14 percent, and wood used indoors should be 6 to 8 percent.

Q. How do I know my moisture meter is accurate?

The quick and easy way to test if your moisture meter is accurate is to check the same area two or three times; results should be consistent. If they aren’t, then recalibration may be necessary. This typically requires contacting the manufacturer. A high-end wood moisture test meter may come with its own calibration device.

Q. What is the best way to measure moisture content in wood?

According to the American Society for Testing and Materials, oven-dry testing is the scientific method, although this is not practical for most. A handheld moisture probe like those featured here meets most needs.

Q. Which is more accurate, a pin or pinless moisture meter?

Both types of moisture meter can be very accurate, but one isn’t necessarily better than the other. You’ll want to check the specification of each device.

Q. Should I go for a cheap moisture meter?

If you’re heating with a wood stove, for example, then your best moisture meter for firewood could be a cheap model because high accuracy isn’t necessary. If your plan is to use it for fault-finding in construction lumber or wood stability for furniture making, you’ll want to invest more to ensure accuracy.
