Hydrosteel 7000TL Transportable Corrosion Monitor
Hydrosteel 7000 Transportable Light (TL) is a newly developed lightweight corrosion monitor for the non-intrusive continuous measurement of hydrogen flux.
A complete stand-alone battery operated kit, Hydrosteel 7000TL weighs just 8 kg, 15 lb. The lightweight instrument has been designed for easy installation at the top of tall refinery towers and columns and enables monitoring for up to 9 months, depending on the user defined data sampling period.
A major benefit is its ability to monitor active corrosion and hydrogen risk damage, non-intrusively. This is particularly useful for sour, HF and high temperature corrosion events which occur over timescales of days, weeks and months.
Highly accurate, the Hydrosteel 7000 TL corrosion monitor provides the most sensitive, precise hydrogen flux measurements available. Hydrosteel 7000 TL operates without any human intervention, and responds to corrosion changes within minutes.
Developed for the continuous monitoring of hydrogen activity, Hydrosteel 7000 TL is used within critical refinery sites suffering from sour corrosion and risk of hydrogen damage. Target industries for Hydrosteel 7000 TL include refineries, gas plants, gas oil separation plants and chemical industries using petrochemicals containing sour gas, and ammonia production.
