Moisture can cause a lot of problems. The quality and properties of materials depend on the moisture content. No matter whether we work in construction, or working with wooden products. We have to make sure that the moisture or humidity level is up to the given standard.

An excellent way to determine the quality and prevent costly damages is to determine the moisture levels accurately.

To do so, we need to have the best moisture meter. It is basically a very simple tool that helps us determine the presence of moisture in wood, furniture, buildings, homes, or any given situation.

Let’s get started.

Best moisture meters

Buying the best moisture meter depends on what situation you are in. If you are a professional and looking for something that would help you in your field then the moisture detector needs to have high quality and useful features.

The best moisture meter that I and field professionals recommend is either the FILR MR77 or the Protimeter BLD5365. They are the best because they come from proven brands, are used by thousands of people, are reliable, are of high quality, and the best part is they have a very decent price tag that almost anyone can afford.

In case, if you are looking for a cheap alternative that gets the job done without breaking the bank. Then the moisture meter MM8 from General Tools is for you.

In the rest of the article, I talk about these models in more detail.

How I came up with these models. Well, the following are the choosing parameters and criteria that I followed.

Choosing the best moisture detector

Here are a few technical parameters you should keep in mind to make sure you make the best possible purchase for your project requirements.

a. Accuracy

Accuracy is one of the most important parameters when it comes to measuring moisture. Taking accurate readings can make or break the functionality of a meter.

The general rule for any moisture meter is to look for a meter that has an accuracy range from 1 percent to 5 percent. Anything above 5 percent is too inaccurate for general use.

High-end moisture meters can detect moisture lower than 1 percent which makes them extremely precise and accurate.

b. Type of moisture meter

These are essential two types of moisture meters 1) pin type and 2) pinless type. With pin type, you have to insert the pins of the moisture meter into the surface of wood or other under-measurement surfaces. The shorter the probes, the less accurate the readings, and vice versa. So choose it when you are working with smaller pieces of wood or wood with shapes.

On the other hand, a pinless meter can measure moisture content without any probes. This is much easier to use than the above and is best for plane surfaces.

So select your moisture meter according to your situation.

c. Moisture range

It is the range of moisture content a moisture meter can detect with accuracy. Now we want this range to be as high as possible.

For flooring installation, woodworking, and furniture working, this moisture range must be from 6-7%. Not a lot of moisture meters can do this, so always keep an eye on this range.

d. Usability

No matter how good a moisture meter is if it is not easy to use, Chances are you won’t be able to take full advantage of its functionality.

Most of the people who are buying a moisture meter do not know how to use them. So an easy-to-use device will be better than a compact device with a poor user experience.

A straightforward easy-to-use device is always a plus point and something to keep in mind before buying a moisture meter

e. Versatility

The versatility of a moisture meter is determined by its range. If a moisture meter has a wide range that means it can be used with a variety of different materials.

A good moisture meter should be able to operate on a variety of materials ranging from wood to concrete, drywall, and many more materials

f. Other cool features

This includes a good display, a temperature sensor, a built-in humidity sensor, and the ability to hold readings, etc.
