[0002] A metal spectrometer is an instrument used to measure the radiation spectrum of a luminous body, that is, the index parameters of the luminous body itself. The analysis principle of the metal spectrometer is to absorb the characteristic spectrum of the element to be measured emitted by the light source through the ground state atoms of the element to be measured in the vapor of the sample, and then calculate the content of the element to be measured in the sample by the degree to which the emission spectrum is weakened. After searching, the patent with application number 202222047615.2 discloses a spectrometer for metal analysis, which includes an instrument body and a handle, the handle is fixed to the lower end of the instrument body, a protective groove is opened at the right end of the instrument body, a probe is connected to the inside of the protective groove, a cover assembly is provided on the outside of the protective groove, a storage groove is opened at the upper end of the instrument body, a display screen is provided in the storage groove, a handle is fixed to the upper end of the display screen, the right end of the display screen is connected to the right side of the storage groove through a damping hinge, a snap assembly is provided at the left end of the display screen, and a magnetic assembly is provided above the display screen.
