Description
High-Purity Graphite Rotating Disk Electrode for Accurate Oil Spectrometry
SHJ CARBON manufactures precision graphite rotating disk electrodes (RDE) specifically for RDE-AES oil emission spectrometers. Our electrodes deliver reliable detection of wear metals, pollutants, and additives in industrial oils and fluids. They help equipment managers monitor machine health and ensure fluid quality.
We use only high-purity graphite with ultrafine particle structure. This guarantees low ash content and exceptional thermal stability. You get clean, consistent results with every test.

Key Features of Our Graphite Electrode
Our graphite rotating disk electrode offers important advantages for oil spectrometry and electrochemistry:
- Made from 99.99% high-purity graphite for contamination-free analysis
- Designed with a central mounting hole (0.125 inches) for secure placement
- High thermal resistance (up to 4350°F) and low thermal expansion
- Dense structure with fine surface finish for accurate spectral readings
These features make the electrode ideal for preventive maintenance programs. It fits spectrometers from major brands like Spectro Scientific, MOA, and GNR.
