Introduction to the working principle of wood moisture meter
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 the moisture of wood 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.
How to use the wood moisture meter:
1. Gear setting method: first press the gear setting button (SPECIES), and then press the test button (TEST). At this time, the current gear value is displayed. Press the setting button continuously to change the gear continuously until needed. stalls.
2. Check before measurement: Set to level 5 according to the above method, then pull out the cap of the instrument, touch the probe on the instrument to the two contacts on the cap, press the test key, if the display is 18±1, it means The instrument is normal.
3 Measurement: Insert the probe on the instrument into the wood specimen to be measured. Press the test button, the value displayed by the instrument is the average moisture content of the specimen, when the moisture content of the specimen is less than 3, it will display 3.0, and when the moisture content of the specimen is greater than 40, it will display 40, which means it has exceeded the range.
