Rotroil is an optical emission spectrometer designed to determine the trace concentration in wear metals, polluting materials and additives in lubricating oils, transmission and refrigerating liquids.

Determination of such components is very important in order to be able to make preventive maintenance and avoid the mechanical parts to break while in motion. Thanks to twenty years of experience, GNR, leader company in optical emission spectrometry's field, can offer an instrument that, using the traditional technique of rotating electrode sampling, employs the most modern technologies both for hardware and software.

The spectrometer is an highly precise and reliable product able to satisfy the demanding international rules.
