Product Descriptions
HALL EFFECT MEASUREMENT SYSTEM is used to measure the important parameters of Semiconductor Materials such as Carrier Concentration, Mobility, Resistivity, and Hall Coefficient, and so on. These parameters must be grasped and controlled in advance in order to understand the electrical characteristics of semiconductor materials. Therefore, the Hall Effect Measurement System is an indispensable tool for understanding and studying the electrical characteristics of Semiconductor Devices and Semiconductor Materials. The experimental results are automatically calculated by the software, and the Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient, Magneto-Resistance, and other parameters can be obtained at the same time.
Product Description
The static magnetic field active shielding system can offset the magnetic field fluctuations of the geomagnetic field in real time, thereby generating a 10nT zero magnetic environment in the geomagnetic environment. For example, the gradient magnetic field of 1nT or 0.1nT can be generated in the shielding room or shielding cylinder, the system can also generate any set magnetic field in three-dimensional components for scientific experiments and simulation of geomagnetic changes.
Product Descriptions
The dynamic magnetic field shielding effect can reach a higher level (better than 5 nT). By using AC current to generate a magnetic field, it has higher DC and AC magnetic field shielding efficiency, more accurate trajectory tracking function, larger range, and higher response speed. The ability to generate magnetic fields with three components X, Y, and Z within the range of (0-100000 nT) magnetic fields can be precise up to 5 nT, making products and experiments in scientific research, military industry, and medical care extremely meaningful and widely used.

The Magnetic-Moment-Free Coil is composed of several pairs of coils, which are installed in a certain geometric structure, and of which the certain number of coil’s turns and a certain current direction make the magnetic field outside the Magnetic-Moment-Free Coil attenuate rapidly and make the magnetic moment of the Magnetic-Moment-Free Coil be zero. One of outstanding advantages of the moment-free coil is that it does not produce magnetic interference to the environment outside a certain distance from the Magnetic-Moment-Free coil during operation, which means that it is very significant for the simultaneous operation of multiple systems; In addition, the moment-free coil does not magnetize the adjacent magnetic substance, therefore, it does not bring extra errors to the moment-free coil in this respect.
Clamp Electromagnet, of which the shape is like a vice, has two magnetic poles protruding outside the coils. It is usually used to generate an in-plane magnetic field. It is suitable for special operation environments such as microscopy, probe station, the limited space, magneto-optical experiment, and magnetic mineral powder screening. The Clamp Electromagnet is basically custom-made, and can be designed and produced according to user's application conditions and magnetic field requirements.
This power supply is a high stability bipolar constant current power supply (smooth zero crossing commutation without delay). The power supply adopts a linear power supply structure, with high output current stability, low ripple and noise. The output current of the power supply can be continuously changed between positive and negative rated maximum current, and the current is smooth and continuous zero, which can generate a smooth and stable magnetic field in the electromagnet or coil. With our high precision Gauss meter and probe (optional), the power supply can operate in magnetic field mode. The magnetic field value can be directly set in magnetic field mode,The power supply will adjust the output current to make the electromagnet quickly reach the set magnetic field, convenient and fast, and the magnetic field is stable.It can control the field independently or scan the magnetic field continuously. The current mode and magnetic field mode can be switched at any time according to the need, and the operation is flexible.
The three-axis Helmholtz coil is composed of 3 pairs of Helmholtz coils arranged along three orthogonal axes, which can simultaneously generate uniform magnetic fields in the direction of x-, y-, or z-axis.Helmholtz coils can be customized by through adjusting the coil diameter, required magnetic field, working time, structural requirements, and dissipation requirements (air cooling or water cooling).
