방법 사용 수분 미터 측정 목재 바닥
대신 의 지출 시간 신중하게 건조 나무 샘플 및 무게 그들 to check 그들의 원본 수분 내용, 많은 DIY 매니아 지금 사용 현대적 기술 to quickly and accurately read the percent MC of moving wood.
거기 있다 다양한 유형 의 나무 습도계, 각각 with 많은 다른 특성. 이들 도구 할 수 있다 be divided into two categories through measurement methods:
바늘 유형 기기. 이들 장치 사용 둘 또는 더보기 전극 to measure the moisture content of wood samples. since wood is a natural insulator and water is a conductor, the greater the resistance of electric current, the drier the wood, and vice versa.
Needle free moisture meter. These hygrometers, also known as "non-destructive" instruments by some, use specialized scanning plates to transmit electromagnetic waves through material samples and create readings of the average moisture content in the scanning area.
이들 DIY 수분 미터 유형 가지 둘 다 장점 및 단점.
For example, needle instruments will leave tiny holes in the material they test, as you need to use electrodes to penetrate the surface to obtain a reading. on the other hand, needle free instruments need to make the scanning plate fully contact the scanned material to obtain accurate measurement results.
In most cases, using these instruments is very simple.
To use a needle type wood hygrometer, simply insert the pin into the material to be tested and activate the instrument. The current will be transferred from one pin to another, and the instrument will give a reading based on the current impedance.
Using a needle less instrument, you only need to firmly press the base of the scanning board onto the wood you are inspecting and activate the instrument. 유사하게, the instrument will run a scan and provide you with usable readings.
바늘 less instruments are faster than needle instruments in scanning large areas because they can measure larger areas. in addition, they do not leave pinholes in the tested wood - making them very suitable for measuring moisture in beautiful hardwood flooring.
Some instruments may have more advanced features based on their manufacturer, such as built-in temperature or wood type correction. to use these functions, you may need to consult the personal user manual of the hygrometer.
