How Do Moisture Meters Work
There are many different models and types of moisture meters on the market, but they all work on the same basic principle.
Moisture meters measure the moisture content in wood or other building materials by sending an electrical current through the material and measuring the electrical resistance to that current flow. The more moisture that is present, the greater the resistance to current flow will be.
Types of Moisture Meters
There are two main types of moisture meters: pin type and pinless. Pin type moisture meters have two metal pins that penetrate the surface of the material being tested, making contact with the material beneath.
Pinless moisture meters do not have any exposed metal parts and instead use electromagnetic waves to measure moisture content below the surface.
Both pin type and pinless moisture meters have their advantages and disadvantages, and the type of meter you use will depend on the application.
Advantages of Pin Type Moisture Meters
More accurate than pinless moisture meters
Can be used on a variety of materials
Disadvantages of Pin Type Moisture Meters
Can damage the material being tested
Pins can become corroded over time
Advantages of Pinless Meters
Non-destructive testing — will not damage the material being tested
No pins to become corroded over time
Disadvantages of Pinless Moisture Meters
Less accurate than pin type moisture meters
Cannot be used on all materials
Which One Should You Choose?
When it comes to choosing a moisture meter, it really depends on the application. If you need a more accurate reading and the material can withstand being pierced, then a pin type moisture meter is a good option. If you need a non-destructive test and the accuracy is not as important, then a pinless moisture meter would be a better bet.
Which Industries Use Moisture Meters?
There are a variety of industries that use moisture meters. Some of these industries include:
Building & Construction
Building and construction workers typically use moisture meters to test for moisture in wood and other building materials before starting a project. This helps them determine if the material is too wet or dry to work with, which could affect the stability of the finished product.
HVAC & Plumbing
Moisture meters are also used in the HVAC and plumbing industries. Plumbers may use them to check for leaks in pipes, while HVAC technicians may use them to check for moisture in air ducts.
Moisture meters can also be used in environmental sciences, such as agriculture and meteorology. Farmers may use soil moisture meters to measure the moisture content of soil, while meteorologists may use them to measure the moisture content of the atmosphere.
Wood moisture meters are also used in the woodworking industry. Woodworkers may use them to check the moisture content of wood before they start working with it. These moisture meter readings are important because the moisture content of wood can affect its stability and strength.
