CVM200 Variable Temperature Hall Effect Tester

The CVM200 Variable Temperature Hall Effect Tester by Vectomag is a compact, multi-functional system designed for studying Hall effect, carrier type transitions, and related semiconductor phenomena under variable temperature conditions. It supports both educational demonstrations and scientific research, offering high precision, cost efficiency, and operational simplicity.

Researchers can easily replace pre-mounted standard samples with their own to investigate temperature-dependent magnetoresistance, superconductivity, resistivity characteristics, magneto-optical effects, and other advanced materials behaviors.

Its modular design makes it ideal for university physics laboratories, materials research centers, and electronic device development.
