We are dealing in 2 optical emission spectrometers which are applicable for materials analysis, environmental monitoring quality control, and scientific research. Supplied devices allow for accurate, versatile and quick elemental analysis competences. The said devices allow for high precision and accuracy and bestow accurate quantitative analysis of a several elements. 2 optical emission spectrometers are made to perceive elements at low concentrations, making it appropriate for environmental analysis as well quality control. These can also study the concentration of elements such as copper, aluminum, iron, nickel, and others.
