Distinguish between needle type and induction type wood moisture meter. Do you know what is the key point?
The wood moisture meter is used to measure the moisture in wood, wood products, construction, food and other industries. Moisture measurement of conductive substances. According to the details, the wood moisture meter may be divided into a pin type wood moisture meter and an inductive wood moisture meter. Whether it is a needle type or an induction type, it belongs to the wood moisture meter, and both are suitable for on-site moisture detection. Even so, there are many differences between the two:
The difference between the induction type and the needle type of the wood moisture meter
1. The difference in appearance: the sensor types of the two are different, one is a pin type, and the other is an inductive type. Inductive is a measurement method that uses non-destructive detection. The dielectric constant of the measured object is measured by high-frequency electromagnetic waves, thereby measuring the moisture content of the measured object. The pin type is measured with a pin type. By measuring the conductivity between the two probes, the moisture content of the measured object can be measured.
2. The difference in the number of measurement codes. There are 10 types of needle codes, and 20 types of inductive codes.
3. The difference in the measurement range: the measurement range of the needle type wood is 0-80%, while the range of the induction type is 0-70%
4. Destructive difference: In the inductive test, only the induction probe needs to be pasted on the surface of the measured object, without any destructive effect on the measured object; in the pin type, the instrument probe needs to be inserted into the measured object, which will destroy the The surface of the measured object.
