HSPM-07RT Room temperature permanent magnet Hall test system is composed of high precision Hall tester, room temperature permanent magnet fixture platform, test computer and software，Hall effect can be measured under fixed magnetic field，System structure Desktop structure design, small size，High test efficiency，It is the best choice for rapid laboratory testing and factory quality inspection。The system has a 77K liquid nitrogen single point option to provide samples for Hall effect measurements at 77K low temperatures。

  The system adopts scientific and reasonable common ground design, and the internal electrical signal lines all use three-coaxial cables to ensure the measurement of high-resistance semiconductor materials, and can accurately measure the important parameters of the sample carrier concentration mobility, resistivity, Hall coefficient and so on。Room temperature permanent magnet fixture platform, can easily move and flip the magnetic field, can meet the fast hall and DC hall test, using PCB pluggable sample card design, taking into account Vanderbilt and Holba samples。

System features:
• Magnetic field is better than 0.7T (room temperature measurement);Magnetic field better than 0.5T (Liquid nitrogen single point option)
• The permanent magnet moves through the slide rail and can be easily flipped while taking into account both fast Hall and DC Hall testing
• Simple pluggable sample card design for fast and easy sample handling and Hall testing of both Holba and Vanderbilt samples
• Sample card includes spring beryllium copper probe four probe card, bent tungsten probe four probe card and welded sample card to meet different sample testing requirements
• Scientific and reasonable common ground and triaxial structure design ensures the high resistance test performance of the system, and the resistance can reach 100GΩ
• The test chamber has a gas path valve, which can pass nitrogen and argon for protection, and can also extract vacuum
