Hydrosteel® 6500: Advanced Hydrogen Flux Corrosion Monitor

The world’s first multipoint hydrogen flux monitor

Hydrosteel® 6500 is the industry’s leading instrument for real-time hydrogen flux measurement and corrosion monitoring in extreme environments. Using innovative magnetic probe technology, it captures flux directly from steel surfaces, delivering rapid, reliable data to optimise maintenance and corrosion control strategies. Ideal for petrochemical, refinery, and sour gas applications, this robust device supports both spot measurements and continuous monitoring, ensuring operational safety and reduced downtime.

Hydrogen Flux Monitoring Technology

At the heart of Hydrosteel® 6500 is patented technology (GB2538113) that revolutionises corrosion monitoring. Our system uses a uniquely-designed magnetic attachment to secure a flexible metal plate directly onto steel surfaces. This ensures intimate contact without permanent modifications, allowing for the real-time capture of hydrogen gas – a direct indicator of corrosion.

Hydrosteel® 6500: Operation and Advantages

By drawing ambient air between the plate and the steel, the system collects hydrogen emanating from the metal. This captured gas is then analysed by a highly-accurate sensor, providing immediate measurements of hydrogen flux. Unlike traditional methods that rely on wall loss or corrosion coupons, our technology delivers high sensitivity and reliable data, directly from the service steel.

This innovation not only enhances measurement accuracy, but also enable multipoint continuous monitoring. Whether you need quick spot checks or ongoing corrosion surveillance across multiple locations, Hydrosteel® 6500 offers the flexibility and precision required, even for the most demanding industrial environments.
