How Wood Moisture Meters Work
The wood moisture meter adopts microwave measurement technology, which can determine the moisture within 1 second. The measurement result is highly accurate and is not affected by the particles, colors and any minerals contained in the product. It is made by using the principle that microwave energy is attenuated by being absorbed when passing through a substance. It can be used to measure the moisture of coal powder, petroleum or various crops; check the humidity of the grain depot; and the determination of wood moisture is determined by the principle of resistance, and it takes a considerable time before the wood is dry. During construction, wood that has been processed and dried insufficiently will deform later and cause cracks. Judging from the use examples of historical buildings, hundreds of years of service life have proved that if construction methods and management are ignored, no wood can be an excellent material. In order to be suitable for the high-temperature and humid climate like our country, the humidity of wood changes with the environment, so it is considered as living wood. Moisture management is necessary even if the correct application of wood does not revive it.
Calibration method
①Wood preparation: Take ten varieties of wood to be tested.
②According to the instrument used, refer to the instructions of the corresponding type of wood moisture tester, and measure the moisture of various woods according to the regulations.
③ Fill in the measured data into the instrument moisture column in the moisture detector calibration table.
④Divide each tested wood into two parts, and use the balance oven method to measure the moisture content.
