High Performing Metal Analyser

The ARTUS 8 fulfils the requirement of proving fast, precise and accurate analyses for the perfect melt. It is one of the most powerful and reliable spectrometers offering a complete range of analytical programs including cast irons, steels with carbon and nitrogen, and all alloying elements and their traces needed for treatment.

It offers all the advantages of a flexible and versatile CMOS spectrometer. It even challenges some applications with classical photomultiplier systems, which are still the benchmark in high-end OES.


Quality Control and Assurance are essential to making your business successful. The ARTUS 8 is the ideal companion for incoming material, in-process testing, independent laboratory testing and final quality inspection. it is widely used in the steel manufacturing, cookware, automotive, aluminium extrusion, cast iron and carbon steel industries.

Risks such as material mix-ups and machinery damage are reduced thanks to adapters which detect and analyse oddly shaped samples and small pieces and the optimisable grade library which visually displays non-compliance alloy specifications.
