Technical Field

[0001] The utility model relates to the technical field of test benches, in particular to a multifunctional adjustable test bench. Background Art

[0002] Thickness gauging is a test used to measure the surface or internal thickness of an object. It is widely used in various fields, including manufacturing, construction, aerospace, chemical engineering, and shipbuilding.
