Why do I use a wood moisture meter?
This may be a common question among users who are using a hygrometer for the first time. Although the specific answer to this question may vary by industry, these answers are usually related to quality.
Using a wood hygrometer, you can accurately evaluate the problems that a given sample of wood may encounter, such as cracking, shrinkage, splitting, mold growth, etc. When the moisture content of wood is too high (or even too low, in some cases), the quality of the final product will be affected.
The use of a hygrometer can help you ensure that the moisture content of the wooden material used is within the correct range of% MC to avoid future callbacks.
What are the different types of wood moisture testers?
Although there are countless hygrometer models on the market, and new hygrometers have been emerging, they are divided into two categories based on their operation:
Needle pitch.
Needle free rice.
A needle hygrometer uses two (or more) electrodes to penetrate a wooden material to read the% MC of the material using the principle of resistance. In a two pin instrument, one pin emits current and the other pin receives current, and the instrument interprets the impedance of the current to the current. Due to the fact that wood is an insulator and water is a conductor, the smaller the resistance of the current, the higher the moisture content of the wood.
On the other hand, needle free meters use electromagnetic radio wave scanning instruments to scan wood samples below the board. These instruments are sometimes referred to as non-invasive hygrometers because they do not need to physically penetrate the surface of wood to obtain readings.
What type of moisture meter is better?
After asking about different types of moisture meters, most people still want to know which type of moisture meter is a good one. The answer largely depends on the type of work you are working on, the size of the wooden material you are using, whether pinholes are left in the material, and your personal preferences.
The needle less instrument has fast speed and will not damage the surface of the scanned material. On the other hand, pins can provide you with more specific information about the distribution of moisture in wood.
Many professionals use two types of instruments in their work and switch between them when necessary.
