Ferrous iron, ferric iron, sulfide, and the full suite of corrosion indices, measured on-site in 1-24 hours. Built for integrity engineers, corrosion specialists, and chemical treatment programs that need a same-day decision.
Corrosion is rarely caused by a single agent. In real-world systems, it is the interaction between iron speciation, sulfide presence, dissolved oxygen, scale-forming minerals, and water chemistry stability that determines whether a pipe survives or fails. Retego Certus COR measures the full panel of corrosion-relevant parameters and applies industry-standard predictive indices to give an integrity engineer or chemical treatment professional the complete picture in a single visit.
The result is a field-deployable diagnostic suite that can answer the real corrosion question at the wellsite, in the plant, or at the customer's facility. Not, “Is there corrosion?” but “What kind? How aggressive? What treatment?”
Refinery Cooling Water Programs
A refinery cooling water program runs the full corrosion panel weekly at multiple sample points. The scaling and stability indices drive a real-time adjustment to chemical treatment instead of a monthly retrospective.
Midstream Pipeline integrity
A pipeline integrity engineer pairs Retego Certus COR with Retego Certus SRB at each pig receiver. Receive same-day data on both chemical and microbial corrosion drivers. Treatment programs adjust on the field engineer's next call.
Commercial Boiler Diagnostics
A commercial mechanical contractor diagnoses a boiler scaling problem on-site in a single visit. Langelier and Puckorius indices identify aggressive water; the treatment recommendation is written before the customer signs the visit ticket.
