HSPM-05VT Variable Temperature Hall Test System consists of a Hall tester, a liquid nitrogen storage thermostat and a permanent magnet movement mechanism, which can provide a continuous variable temperature and 0.5T vertical magnetic field test environment from 80K to 500K for samples, and it can test Hall parameters under variable temperature, which is a great convenience for scientific experiments that require both low and high temperatures. This is a very cost-effective, but also the use of more users Hall test system, can achieve a wide range of temperature testing, can also be equipped with other meters, as a pure temperature environment and magnetic environment for other tests.

Features:
- Dual layer sample holder design with an optical sample holder on the bottom and probe holder functionality by adding a four probe plus four lug sample holder cover. Terminal support
The addition of a six-probe holder allows for the simultaneous testing of Holba and Vanderbilt samples.
- Fitted with an adjustment bracket to adjust the vertical position of the thermostat.
- A magnet shifting device allows the permanent magnet to be moved back and forth and turned over.
- Sample chamber can be opened quickly to change samples.
- Liquid nitrogen can be easily filled through the liquid nitrogen refill port on the top of the thermostat, and the refill of liquid nitrogen will not affect the temperature control of the system.
- The thermostat is equipped with a liquid nitrogen flow adjustment lever, which can be used to adjust the thermostat's cooling capacity.
- Leakage current is less than 1pA@1V when used with cryogenic coaxial cable and triaxial/SMA connectors.
- Built-in heaters and sensors work in conjunction with an external thermostat to achieve variable temperature and temperature control of the cryostat.
