Core Technology

30 Seconds, Zero Argon, Zero Preparation

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.

⚡
Rotating Disc Electrode (RDE) Technology
The RDE technique enables direct oil analysis without sample preparation, delivering ppm-level accuracy.
💨
Zero Argon
While most competing RDE instruments require argon, RotrOil runs on mains electricity alone — simplifying logistics and lowering operating costs.
🎯
Factory Calibrated — Plug & Play
Ready to analyse immediately after installation. Fully compliant with ASTM D6595-00 and ASTM D6728-01 standards.

Frequently Asked Questions

What You Wonder About

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.
