induction wood moisture meter and insertion needle wood moisture meter

induction wood moisture meter , insertion needle wood moisture meter

Wood moisture meter is generally divided into two categories: induction wood moisture meter and insertion needle wood moisture meter. The working principle of the pin-in wood moisture meter is to measure the resistance between two points of wood, and then to convert the data to show that its advantage is cheap, but the accuracy is not too high, and after measurement, there will be small pinholes on the surface of wood, often used in low-demand measurement occasions. The working principle of inductive wood moisture meter is electromagnetic wave (high cycle wave) induction. The instrument has an inherent frequency. The moisture content of the measured object is different. The frequency in the sensor transmitter is different. The difference between the two frequencies is that the current is converted by frequency current converter and then converted into digital display by analog-to-digital converter. Its advantage is that the measurement accuracy is higher and there is no damage. It can also be nondestructively measured even if the wood surface has been painted. It is especially suitable for the rapid determination of moisture content in furniture, floor, wooden door, etc.
