The Importance Of Moisture Measurements

Assess Damages

The number one reason why moisture levels are measured is to assess the damages. It helps to get to know the extent of the damage as well as those areas that are hardest hits. This equips you with the information you require to make the necessary interventions.

Mitigate Further Damage

By knowing the extent of the existing damage, it may be possible for you to mitigate further damage. This is because such knowledge helps you to map out the affected areas and make projections on the areas that are more likely to be affected next.

Take Appropriate Proactive Steps

Definitely, such measurements will empower you to take proactive steps that are aimed at lessening the existing damage and preventing any further damages. By knowing the extent of the damage, you will be able to devise the steps necessary to forestall further damages.

Determine the Affected Areas

Taking these measurements will definitely help you to determine the affected areas of your homes, walls or furniture. Such a piece of knowledge will usually empower you to contain the damages effectively. They also help you to devise the necessary preventive steps.

Prevent Attendant Accidents

By knowing how badly your furniture, floor or wall is affected, it is possible for you to prevent any accidents that ordinarily arise thereafter. This is because you will know the portions of these areas of your homes that are worst affected and how to stay away from them.

What Is A Moisture Meter

A moisture meter is a special measuring device which is used to detect the amount of moisture on a surface.

These surfaces are walls, pieces of furniture, the floor, and even heavy upholstery like the carpets.

They display the readings on some display units for you to view.

Benefits Of Moisture Meters

Compact in Size

Most moisture meters are compact in size. They are subsequently easier to carry around as the need may require. This is not to mention that they take up less storage space and are therefore convenient to make good use of.

Simpler to Operate

The typical measuring meter is designed for use by a do-it-yourselfer. As such, it is devoid any sophisticated parts and components that more complex machines possess. For these reasons, they are simpler to operate and do not require too much technical expertise.

Comes up with Accurate Measurements

At the core of their benefits is the fact that they allow you to come up with very accurate measurements. They are designed to be highly responsive and able to respond to the least of triggers and impulses.

Require no Prior Installation

Most of these meters are availed when fully assembled. As such, they require no prior installations or assembly on your part. They are on the contrary ready to go and easily deployable for use. This is great if you have limited time at your disposal or lack the relevant technical expertise.

Aids in Restoration

If you have suffered severe water damage, you will generally find the moisture meters great possessions. This is because they play a great role in restoring these parts and components to their original or rightful working conditions.

Types Of Moisture Meter

Many kinds of moisture meters do abound. However, three of these kinds stand apart from the rest. They are outlined and explained here below:


This kind of meter measures the percentage of the moisture contents at the depth of the head of the respective contact pins. They possess two pins which penetrate the surfaces to be measured of the moisture. It is mostly useful for surfaces that are penetrable.


Unlike the pin-type counterpart, this one lacks the pin. Instead, it makes use of the electric impedance to detect the moisture. As such, it is non-invasive and hardly damages the objects to be measured. Its over-reliance on electrical power to operate, it is not so reliable in the long run.


As the name suggests, this one incorporates the vital traits of the pin-type and the pin-less kinds of moisture detectors. With regards to this, it can function both manually and electrically at a time. It is hence all the more convenient to utilize and rely on.

How Does A Moisture Meter Work?

The workings of the moisture meter depend mainly on its type. A pin-type moisture meter will pierce the surface to be measured using the pins. These pins pick up the signals or traces of moisture and relay the same to the body of the device for interpretation. Upon interpreting the incoming signals, the device showcases the outcomes on the display unit.

As for the pin-less types, the detection of moisture is carried out mainly by the use of electrical impedance. This refers to the resistance of an electric circuit whenever an obstacle is confronted. This resistance is picked up and interpreted. The final outcomes are displayed on the screen for you to see.

How To Use Moisture Meter

Given the variations in their working mechanisms, the manner in which the meters are used varies slightly from one type to another. The following however are the major steps and procedures to make use of a typical moisture meter:

Power the Moisture Meter

Commence by switching on the moisture meter. This is to activate it to let it be able to detect moisture. Simply identify the location of the power button and engage it appropriately to do so. You might have to change batteries if need be.

Insert the Pins on the Surface

Now insert the pin on the surface to be measured. In case yours is the pin-less type, place the meter as close to the surface as possible to obtain more accurate outcomes. You may need to sway the meter back and forth a designated area for the sake of comprehensive cover.

Leave to Rest for Some Time

Leave the meter to rest on the said surface for quite some time. This is necessary to give the device some time to be able to take deeper measurements on the whole. 1 or 2 minutes would be sufficient for this kind of purpose on the whole.

Take the Readings

Now finish off by taking the readings. Simply skim the display unit and the transfer the readings to a record or a piece of paper. You are now good to go!

What Should I Look When Choosing A Moisture Meter?

The following are some of the factors that will definitely help you to make the right purchasing decision:

Type of Meter

As stated, these meters come in three main kinds. These are the pin, pin-less and the all-in-one respectively. It is in your best interest to determine the kind you are comfortable working with to be able to arrive at the best decision. An all-in-one would be better as it is more comprehensive.

Surface to be Measured

Different surfaces require different kinds of measuring devices. It is necessary to ascertain the kind of surface or surfaces which you might want to use these devices on. This will give you a rough clue on the kinds of meters which might be of relevance to you.

Measuring Depth

The depth at which you intend to impact also has a bearing on the kind of meter to use. Be sure therefore to find a meter which is powerful enough to reach out to the deepest depths available. Check out the ratings to be able to ascertain this particular aspect.

Intended Frequency of Use

How often do you intend to use this moisture meter? Is it only for a one-time application or do you intend to use it repeatedly? Needless to say, a durable meter may be useful for repeated uses. This is to take care of the various elements of wear and tear that arise in times of use.

Nature of Application

Industrial applications are generally tough and tedious. In light of this, they call for meters that are equally tougher and more durable. The opposite is applicable for those meters that are intended for ordinary home use and applications.

Frequently Asked Questions (FAQs)

Q1. What is a normal moisture reading?

Normal moisture readings usually range from 5-40%. 5-12% is regarded as optimal whereas 17% is generally considered moderate and acceptable.

Q2. What does a moisture meter measure?

It measures the percentage of moisture in any given substance or surface. This information may be used to ascertain whether that material is ready for use, too wet or dry, or in need of further inspection.

Q3. Is it possible for a moisture meter to detect mold?

Yes, they can! The growth of mold is directly determined by the amount of moisture that is available on a surface of interest. By knowing how much moisture there is on a surface, it is possible to detect the growth of mold.

Q4. What moisture levels grow the mold?

Any moisture level that exceeds 60% creates a conducive environment for the growth of molds.
