RDE-OES Oil Metal Analysis Spectrometer
A rotating disc electrode OES spectrometer that determines wear metals, additives, and contaminants in engine oils, hydraulic fluids, coolants, and fuels at ppm level in 30 seconds. Zero argon, zero sample preparation.
Core Technology
Standard ICP or OES oil analysis requires 30–60 minutes of sample preparation. RotrOil analyses the oil sample directly and delivers results in 30 seconds — without argon.
Model Comparison
All three models deliver the same analytical quality. The difference lies in portability, embedded PC, and automation capacity.

Frequently Asked Questions
Engine oil, hydraulic fluid, gear oil, coolant (antifreeze), fuel (diesel, gas turbine), grease, and process water can all be successfully analysed.
No. RotrOil operates with zero argon consumption during analysis and optical stabilisation, completely eliminating gas supply logistics and costs.
R2's compact, portable design (55 kg) suits field and mobile use; R3's embedded PC and rugged housing meet military standards; R4's 48-sample automatic carousel serves the automation needs of high-volume laboratories.
ASTM D6595-00 (wear metals in used oils), ASTM D6728-01 (contaminants in fuel), and DoD JOAP (Joint Oil Analysis Program) are all fully covered.
