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.
General Description
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.
Applications
Used Oil Analysis
The series is well suited for used lubricating oil analysis to identify abnormal wear, metallic contamination, and additive depletion. This supports preventive and predictive maintenance programs in industries that rely on engines, gearboxes, hydraulic circuits, turbines, and heavy rotating equipment.
Hydraulic Fluid Monitoring
Hydraulic systems benefit from quick elemental screening because rising metal levels or contamination can indicate component wear, fluid degradation, or cleanliness issues. The QualiRDE™ family helps maintenance teams respond earlier to pump, valve, and system problems.
Fuel Contamination Screening
Selected models in the range support screening for contaminants and corrosion-related materials in gas turbine and diesel fuel workflows aligned with ASTM D6728. This is useful for identifying metallic contamination that may affect equipment health or fuel performance.
Broad Industrial Fluid Monitoring
The broader lineup extends beyond lubricating oils to hydraulic oils, gasoline, diesel, heavy fuels, greases, antifreeze, industrial water, domestic water, and steam turbine condensate. That makes the category relevant for transportation, marine, mining, aerospace, power generation, defense, and commercial testing labs.
Standards
The category aligns with internationally recognized ASTM methods referenced throughout the product family.
- ASTM D6595 – Determination of wear metals and contaminants in used lubricating oils or used hydraulic fluids by rotating disc electrode atomic emission spectrometry
- ASTM D6728 – Determination of contaminants in gas turbine and diesel engine fuel by rotating disc electrode atomic emission spectrometry
