Ferrous iron, ferric iron, sulfide, and the full suite of corrosion indices, measured on-site in minutes. Built for integrity engineers, corrosion specialists, and chemical treatment programs that need a same-day decision.

A refinery cooling water program runs the full corrosion panel weekly at multiple sample points. Scaling and stability indices drive real-time chemical treatment adjustments instead of a monthly retrospective.

An integrity engineer pairs the Corrosion Assay Kit with the SRB Detection Kit at each pig station. Same-day data on both chemical and microbial drivers. Treatment programs adjust on the field engineer's next call.

• A water sample is taken from the system.
• Water is added to a test tube containing a brass or carbon steel spheres.
• Brass (copper) test is for potable water applications. Carbon steel is commonly found in industrial and oilfield applications.
• Test tubes are placed on a rocker, which continuously mixes the water and spheres.
• Carbon steel is mixed for 2 hours and brass is mixed for 24 hours.
• After the test, water from the tubes is added to a cuvette (see POST sample).
• Water without exposure to the metal is added to a reagent cuvette (see PRE sample).
• Cuvettes contain reagents that react with iron or copper.
• This is some text inside of a div block.

• It is normal for the PRE sample not to exhibit a color change.
• Systems can be constructed from plastic pipes, and have limited steel and brass piping or fittings.
• Cu and Fe from corrosion will be diluted to low levels.
• No positive reaction is observed. However, the water can be corrosive.
• The intensity of the color is proportional to corrosion rate.
• Determine copper and iron concentration by comparison to standards.

• Results provide a real-time measurement of corrosion rate.
• Test can be used to determine corrosion rate of copper and carbon steel.
• Method is suitable for commercial, domestic and industrial applications.
• Corrosion inhibitor treatments can be optimized using this method.
• Test is suitable for applications where corrosion is caused by oxygen.
• A method is in development for oil and gas applications where CO₂ and H₂S cause corrosion.
