Description

DSM-10 Magnetic susceptibility meter

Application
DSM-10 is used to measure the magnetic susceptibility of rocks. Because of its high sensitivity, it can be used to measure rocks with low magnetic susceptibility, and it can also be used to measure antimagnetic substances. Within a few seconds after turning on the instrument, the sensitivity will reach the highest value. By using precise and complex signal processing methods, the instrument can effectively reduce the influence of external electromagnetism. This instrument is light in weight and small in size, which is easy to carry outdoors.

Product Description
1.The magnetic susceptibility meter is sealed in a box, and the front of the box is a panel with buttons and a liquid crystal display. In order to get the correct measured value (unit SI), the user must multiply the measured value by the constant 10^-6.

2.The indicator light on the instrument indicates the operation of the instrument. There is a small hole reset key on the right side and a USB interface connected to the computer. The instrument is equipped with a communication cable.

3.The instrument has a built-in oscillator and coil, and the frequency of the oscillator varies with the distance from the instrument to the rock. The change of oscillation frequency is directly proportional to the magnetization coefficient of rock. In order to find the change, it is necessary to measure the frequency of twice oscillator. The first measurement close to the rock is called the receiving step. The second measurement is far away from the rock (exposure measurement), which is called compensation step.

4.After the second step is completed, the two numbers are subtracted and displayed.
