CVM-200 Hall Effect Testing Device (System)Detailed product description：

The CVM-200 Hall Effect Testing Device (System) is a new type of instrument for university physics experiments, with the following characteristics:

Progressiveness of the content: The study of Hall effect is an important subject in physics and has great application prospects.
Progressiveness of experimental means: the sample current, Hall effect tester and digital voltmeter are integrated to meet the requirements of both standard samples and Vanderberg sample measurement. Changed the outdated measurement methods of various devices used for measuring the Hall effect, such as large volume, numerous switches, and complex wiring.

Scalability of application scenarios: The CVM-200 Hall effect tester has a wide dynamic range from 0.1nA to 200mA, a high-precision constant current source output with six adjustable ranges, and the measurement capability of a high-precision digital voltmeter with a resolution of 1 μ V, making it flexibly applicable to experiments and scientific research in many fields.
Can directly display the transition of conductive materials.

The measuring instrument mainly consists of the following four parts:
Reversible permanent magnet
CVM-200 Hall Effect Tester (including 1 sample current source with 0.05% accuracy, 1 Hall Effect Tester, and 1 digital voltmeter with 0.05% accuracy)
SV-12 Variable Temperature Thermostat
TC-201 temperature controller
Hall probe, mercury cadmium telluride single crystal sample and connecting cable, etc
