Project Delivery | GoGo Instruments Delivers Externally Adjustable Probe Heating/Cooling Stage to Peking University Shenzhen Graduate School


As per the client's requirements, GoGo Instruments has delivered an Externally Adjustable Probe Station to Peking University Shenzhen Graduate School. This Externally Adjustable Probe Station is a product designed for electrical testing of materials at different temperatures. It can characterize the changes in the electrical properties of materials during both heating and cooling stages as a function of temperature.




This externally adjustable probe station utilizes the micrometer head structure of external probe modules to achieve XYZ-direction displacement, allowing probes inside the chamber to be adjusted with micron-level movement. The movement modules are designed outside the chamber, ensuring they do not affect the internal environment. Employing liquid nitrogen cooling and resistance heating, it enables precise temperature control within a range of -190℃ to 600. It can be integrated with electrical instruments (such as Source Meters, Multimeters, etc.) to perform in-situ temperature-dependent testing.
