Common problems and solutions with wood moisture meters
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 answers to this question may vary by industry, these answers are usually related to quality.
By using a wood hygrometer, you can accurately evaluate the potential 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.
Using a hygrometer can help you ensure that the moisture content of the wood materials you use is within the correct range of% MC, to avoid future setbacks.
What are the different types of wood moisture testers?
Although there are countless humidity meter models on the market, and new humidity meters have been emerging, they can be divided into two categories based on their operation:
Needle pitch.
Needle free rice.
The needle hygrometer uses two (or more) electrodes to penetrate wooden materials and reads 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 current to current. Due to wood being an insulator and water being a conductor, the lower the resistance of electric current, the higher the moisture content of 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 good. The answer largely depends on the type of work you are doing, the size of the wood material you are using, whether pinholes are left in the material, and your personal preferences.
Needle less instruments have fast speed and will not damage the surface of the scanned material. On the other hand, sales needles 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.
