RDE-OES Elemental Analyzer
RDE-OES analyzers help maintenance teams and industrial laboratories identify wear metals, contaminants, and additive elements in working fluids with fast turnaround. The QualiRDE™ series is built for direct oil analysis, short test cycles, and dependable multi-element screening across used oils, hydraulic fluids, fuels, greases, antifreeze, water-based samples, and steam turbine condensate.
This product family covers multiple workflow levels, from standard routine oil screening to precision arc analysis, compact integrated systems, dual-optic configurations, and ultra-compact platforms. Across the range, the series supports ASTM D6595 and ASTM D6728 workflows, sub-ppm detection capability, direct sample testing without extensive pretreatment, and rapid analysis in 30 seconds or less.
The QualiRDE™ family is a line of RDE-OES elemental analyzers developed for oil condition monitoring, predictive maintenance, and contamination screening. These systems use rotating disc electrode optical emission spectrometry to measure metallic elements in lubricants and related fluids, helping laboratories detect wear trends, contamination events, and additive depletion before they develop into larger maintenance issues.
The lineup includes the QualiRDE™ 800, 800H, 1000, 2000, and 3000. Each model is designed for direct testing from the sample cup with no dilution, no added chemical reagents, and no need for auxiliary gases during routine operation. This helps shorten preparation time and makes the series practical for both central laboratories and field-support testing environments.
Why Choose the QualiRDE™ Series
The QualiRDE™ series is built for laboratories that want fast elemental data without a complicated workflow. Across the family, the systems support analysis times of 30 seconds or less, detection limits below 1 ppm, and software tools for reporting, statistics, calibration support, and trend analysis.
Several models also add configuration advantages for different lab needs. The 800 offers a strong standard platform with holographic grating optics and high-speed data acquisition. The 800H adds precision arc performance, CCD full-spectrum capability, and repeatability within ±10%. The 1000 uses an integrated benchtop format with built-in grinder and communication functions, while the 2000 and 3000 provide dual-optic or ultra-compact designs for higher flexibility and smaller footprints.
