RDE-OES Elemental Analyzer

RDE-OES Elemental Analyzer – QualiRDE™ Series

RDE-OES elemental analyzers are designed to support maintenance teams and industrial laboratories in quickly identifying wear metals, contaminants, and additive elements in operating fluids. The QualiRDE™ series is engineered for direct oil analysis, short test cycles, and consistent multi-element screening across a wide range of samples.

These systems are widely used for used oils, hydraulic fluids, fuels, greases, antifreeze, water-based solutions, and steam turbine condensate. Built for rapid workflows, the platform delivers reliable results without lengthy preparation steps.

The product range includes multiple configurations, supporting everything from routine oil screening to advanced arc analysis. Options include compact integrated systems, dual-optic setups, and high-performance laboratory configurations. Across the series, users benefit from alignment with ASTM D6595 and ASTM D6728 methods, sub-ppm sensitivity, and fast direct analysis typically completed within 30 seconds.

QualiRDE™ Series Overview

The QualiRDE™ family is developed for oil condition monitoring, predictive maintenance programs, and contamination detection. Using rotating disc electrode optical emission spectrometry (RDE-OES), the systems measure metallic elements in lubricants and related fluids to help detect early-stage wear, contamination events, and additive depletion.

The lineup includes models such as QualiRDE™ 800, 800H, 1000, 2000, and 3000. Each configuration supports direct sample testing from the cup without dilution, chemical reagents, or auxiliary gas requirements during routine operation. This reduces preparation time and supports both central laboratory environments and on-site testing workflows.

Why Choose the QualiRDE™ Series

The series is developed for laboratories that require fast elemental insights with a simplified workflow. Most models deliver analysis within 30 seconds, with detection limits below 1 ppm and built-in tools for reporting, statistical evaluation, calibration management, and trend tracking.

Different models are designed for specific operational needs:

• The 800 provides a stable standard platform with high-speed data acquisition and precision optics

• The 800H adds enhanced arc performance, full-spectrum CCD capability, and repeatability within ±10%

• The 1000 integrates a compact benchtop structure with built-in grinding and communication functions

• The 2000 and 3000 focus on dual-optic flexibility and ultra-compact design formats for space-efficient labs
