Learn MoreHALL EFFECT MEASUREMENT SYSTEM
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. -
Learn MoreThe static geomagnetic active shielding system
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. -
Learn MoreThe dynamic magnetic field active geomagnetic shielding system
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.

Magnetic-Moment-Free Coil
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.

Three-Axis Equal-Diameter Coil
The Three-Axis Equal-Diameter Coil, which is a type of three-axis Helmholtz coil exclusively developed by our company, features the nominal diameter coil, the same number of winding turns, and the same specification of wires per axis.<br/> This winding construction allows the Three-Axis Equal-Diameter Coil to have the same resistance, inductance, homogeneity, and B/I coefficient per axis; The coil per axis is fixed to each other in the embedded form, of which this mechanical structure makes the coil to feature a small size and the greater accessibility to the working gap; the whole former is made of non-magnetic PMMA material, which is applied for the study of low and weak magnetic field, and which is very suitable for the shielding room and the magnetic shield. The highest magnetic field of a three-axis equal diameter coil can be designed to be from 0 to 5 Gs.

Halbach permanent magnet
Halbach permanent magnet is a magnetic ring made from a specially arranged array of permanent magnets, capable of generating a strong one-sided magnetic field inside or outside of the ring, while there's almost no magnetic field on the other side. This design significantly improves magnetic field utilization efficiency and is widely used in high-performance magnetic devices such as particle accelerators, magnetic resonance imaging (MRI), and high-precision magnetic measurement equipment.

HEA Series Power Amplifiers
HEA series power amplifiers are specially designed for the use of exciter, which can provide a stable and adjustable excitation current for the exciter.Under the action of the excitation current, the exciter generates an excitation force on the tested component that corresponds to the excitation current, and the magnitude and phase of this force are only related to the excitation current and the characteristics of the exciter itself, but which is independent of the tested component.<br/> HEA series linear power amplifiers has below advantages: stable performance, strong protection function, easy to operation, no impulse during startup, no pollution to the environment, safe and reliable use. In addition, HEA series linear power amplifiers have good adaptability, which is suitable for the impedance of its basic matching load. It is widely used in excitation of inductive loads such as electromagnets and Helmholtz coils.

YPD Series DC Power Supply
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.
