Moisture Meter Buyers Guide

When purchasing the best moisture meter, some factors have to consider, such as-

Pin-style moisture meter

Pin type moisture meter is fitted with two pins at the top that need to be entered into the material to detect the moisture percentage level inside. These models are generally cheaper and have the most accurate readings than the pinless moisture meter. However, the downside to these models is that while testing a pin-style moisture meter leaves small holes into the materials to get a reading. 

Pinless Moisture Meter

Contactless, pinless moisture meters are also known as non-contact moisture meters that measure moisture on the material's surface while sitting on the wood's surface using the sensor or utilizing electromagnetic waves at least 3/4 inches deep.  The pinless moisture meter is entirely accurate and does not puncture the material. One drawback is that they are usually more costly than the pin type. 

Measuring Range

The range of measurement of a moisture meter is one of the essential factors because it is determined by the minimum and maximum moisture percentages it can read. The more comprehensive the measuring range of a rate is, the better because it will provide more precise results. You should look for a product that can measure 6 to 50% moisture content range, especially for flooring and woodworking purposes.

Therefore, the measurement ranges also depend on the type of work, so try to consider a moisture meter with a narrow down measuring range of 7 to 20 % of moisture content so that you will have accurate readings.

Accuracy

Other than the measuring range, accuracy is another most essential feature in deciding which one to buy. Not all moisture meters are as accurate as others and will give accurate results. Please note that the lower this value is, the better the acceptable deviation by a moisture meter ranges within 0.1% increment is accurate. Any device with more than 1% isn't that accurate and should not be considered.

Frequently Asked Questions

Is Moisture Meters Accurate?

Yes, all of the moisture meters in our list can give approximately accurate value measurements of wood and building material moisture content. However, this accuracy is also affected by the quality, model, and moisture meter types.

What Is Moisture Level Acceptable in Firewood?

Below 20 percent moisture level Seasoned firewood is obvious. Otherwise, the wood won't be usable for the fire. 

What is a Normal Reading on a Moisture Meter?

In general, it depends on the type of wood and its purpose. A reading of 5-12 percent is ideal for firewood, where for fresh-cut pine and spruce, it is acceptable up to 15 %. On the other hand, for drywall, needing lower moisture readings of around 5-7 percent; otherwise, it indicates a problem.

Final Thoughts

In conclusion, it's quite clear that many people will require a moisture meter for a variety of different reasons. And the above list of products is the top moisture meter for drywall that has covered all the efficient and accurate devices to suit functions and can confidently be used as a professional.
