Our pick among pinless moisture meters, this Dr. Meter pinless moisture meter for wood uses HF electromagnetic waves to read moisture content in a range of 4-80% and with a precision down to +/-.5%, making it in theory more precise than even the best of the pin type moisture meters on our list.
However, it doesn’t do as good a job as the pin type when it comes to comparing different areas of the same wood piece for moisture content.
This pinless moisture meter is accurate and reliable, and it includes an automatic temperature compensation feature as well as preset calibrations for 10 different densities of wood. Of note however, it lacks a backlight for the LCD, which might make it harder to read in darker environments. These moisture meters are as handy as the good old fashioned best shovel.

How we decided
To help you choose the best moisture meters we only included models that promised a precise reading within at least +/- 3% moisture content for wood and building materials. They also had to feature an easy to read screen with large numbers. Backlighting was considered a bonus, but is an especially useful feature on a moisture meter for home inspection, when you might be using it in dimly lit spaces such as basements.
We also selected only moisture meters that allowed for calibration for different grades of wood– this is important when using a moisture meter for wood slabs or evaluating a lumber purchase. Temperature correction is a nice extra.
Finally, we looked at both pin type and pinless moisture meters; for pinless moisture meters we required effectiveness on both hardwood and softer woods. Pinless moisture meters are handy when inspecting antiques or hardwood flooring.
Moisture Meters Buying Guide
Features to Consider
- Pin Type vs Pinless
Both pin type and pinless moisture meters can deliver reliable ratings of moisture content in a variety of building materials. Pinless moisture meters like our #4 pick, the Dr. Meter MD918, have the advantage when it’s important not to poke or scratch the surface of the material. There’s also no risk of the pins wearing out. Pin-type moisture meters tend to be easier to calibrate and are more useful for locating leaks and potential trouble spots in walls or flooring.
The best moisture meters have large, easy-to-read LCD screens that quickly give you the information you need to know. If you’re looking at a moisture meter for home inspection or flood damage control, look for one with a backlit LCD.
- Calibration options
Some moisture meters are more specialized than others. The General Tools (our #2 pick) offers different settings for concrete, drywall and a few types of wood, while the Tavool (our Top Pick) lets you calibrate for up to eight different densities of wood.
Moisture Meter FAQs
Are moisture meters accurate?
Yes, all of the best moisture meters on our list offer accurate measurements of wood and building material moisture content. Their precision ranges from +/- .2 % to +/- 3 % depending on model and the material in question. Wood has more natural moisture content than drywall.
What’s an acceptable moisture content for wood?
It depends on the type of wood and its purpose. For firewood you ideally want less than 12% moisture content. For fresh cut pine and spruce, up to 15 % is acceptable. On the other hand, for drywall, anything above about 1% indicates a problem that could compromise the structure.
Are pinless moisture meters reliable?
Once calibrated correctly, a pinless moisture meter should give reliable results and in some instances can actually give a more accurate reading.
