SB120/2 Type Four Probe Sample Testing PlatformDetailed product description：

The SB120/2 four probe sample testing platform is an improved version of the SB120/1 testing platform. It consists of a base, a bracket, a rotating component, a sample platform, four probes, and a wiring board. Due to significant improvements in its entire structure and rotation method based on the original SB120/1, it has provided great convenience for the testing and research of the resistance and resistivity of conductors/semiconductors in physics experiments and scientific research in universities.
