Spectroscope
A scientific instrument that decomposes the energy emitted by a material through spark discharge into spectral lines. Since the atomic number of each element is different, the emitted spectrum is transmitted to the optical system and converted into electric charges to measure the ratio of each element.

Universal Material Testing Machine
(Tension Testing Machine)
Test the tensile strength, Yield Strength, elongation of various materials, etc.The purpose is to use the degree of deformation of the material to confirm whether the sample complies with the specifications (AA, ASTM, JIS, CNS).
Sample: Metal sheet
