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.

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.
