OILA-I Oil Emission Spectrometer is as a proven means of  precisely determining elemental composition of  wear metals, pollutants and additives in lubricating oil, hydraulic oil, heavy fuels, coolant and electrolyte. It is used as both a quality control tool and machine health monitor.

Oil Emission Spectrometer, also known as the rotating disc Electrode Atomic emission spectrometer (RDE-AES), is a standard analytical instrument for oil element detection recognized in the global market.

It is specially used to accurately quantify the composition of trace elements in various industrial oils and liquids.

OILA-I provides simultaneous multi-element analysis in tens of seconds without using gases and cooling water.

It is an effective tool for preventive maintenance of equipment.
