Ion Science Hydrosteel 6500 — Hydrogen Flux Monitor for Steel Corrosion Detection
The Ion Science Hydrosteel 6500 measures hydrogen flux through steel — the atomic hydrogen permeating a vessel or pipe wall as a by-product of active corrosion.
That makes it fundamentally different from thickness-based inspection. Ultrasonic and radiographic methods tell you how much metal you have already lost; hydrogen flux tells you whether metal loss is happening right now. The measurement is non-intrusive and non-destructive, taken from the outside of the equipment — no shutdown, no insulation stripping beyond the probe location, and no process interruption.
Supplied as a full kit, it supports large and small probe assemblies for survey work, plus All Temp (AT-S) and High Temp (HT-S) stationary probes for permanent monitoring points, with conduit options of 1 m, 2 m and 4 m.
Probes, consumables and accessories
Large and small probe assemblies, matching collector plate assemblies, AT-S and HT-S stationary probes, 1 m / 2 m / 4 m conduits, probe handle, Staubli adaptor, charger assembly, external 10 V barrier clamp, USB and mains leads, and hard and leather carry cases are stocked in Hydrosteel 6500 Spares & Accessories.

- Non-intrusive and non-destructive — measured from outside the equipment, on-stream, with no shutdown
- Survey and stationary probes — roving inspection plus continuous monitoring points from one instrument
- All Temp (AT-S) and High Temp (HT-S) probe options — stationary monitoring on hot service lines
- Conduit lengths of 1 m, 2 m and 4 m — reaching awkward or elevated locations
- Feeds real decisions — directly informs corrosion inhibitor dosing and inspection scheduling
