Engineered with high sensitivity, stable performance, and broad sample compatibility, this vibrating sample magnetometer supports both manual and automated testing modes, making it ideal for use in university labs, industrial R&D departments, and scientific research institutes.
Introduction
DXV-60 VSM magnetometer stands out in the field of magnetic measurement for its high adaptability, high sensitivity, high precision and high reliability. Not only can automatic intelligent measurement be realized, but also has a series of significant advantages. VSM instrument, as a new magnetic measuring device based on induction principle combined with the development of modern electronic technology, has a unique and efficient working principle. It works by placing the sample in a stable magnetic field environment and causing the sample to vibrate periodically within a small range relative to the detection coil. In this process, the instrument can capture a signal that is proportional to the magnetic moment of the sample under test, then accurately amplify and detect the signal, and finally convert it into a voltage signal that is easy to read and analyze. VSM magnetometer not only has strong adaptability, can deal with the measurement of different types and properties of magnetic materials, and its high sensitivity and high precision characteristics also ensure the accuracy and reliability of measurement results. In addition, the instrument is easy to operate and use, providing great convenience for researchers and engineers.
The VSM magnetometer provides two test methods to meet different
research needs:
Manual measurement: The user directly controls the parameters such as modulation, phase shift, time constant and sensitivity through the buttons on the instrument panel, and the computer does not participate in the control at this time. This method is suitable for scenarios where fine parameter adjustment is required.
Online measurement: The system phase is automatically locked. After the user presses the corresponding key, the instrument automatically returns to zero, and the computer accurately controls the time constant, phase shift, sensitivity, magnetic field strength and the number of scans of the digital magnetic moment unit. This method realizes the automation of measurement and improves the measurement efficiency.

In the user operation interface of the measurement, the sketch of the establishing region of the command button.
It supplies 3 manners of the curve of the measured samples: "Fast Test Curve of M(H)", "Measure hysteresis loop" and "Measure magnetization curve".
"measure warming curve " "measure warming/cooling curve " "measure cooling curve" and "show the change of the temperature as time goes away". Move the mouse to choose the type of measurement curve.
It will supply "Draw magnetization curve", "Draw Hysteresis loops", "Draw Demagnetization curve". "draw the warming curve", "draw the warming/cooling curve", and "draw the cooling curve". Move the mouse to choose the corresponding curve drawing type.
This region will appear when there aren't any files while disappearing in the process of the test and when opening the files. The hardware list and the folder list are in the left region, while the files list of the folder to be opened is in the right region, then choose the curve types which are needed to draw. Then double-click the name of the file to be done. So we can draw then.
