From qualified practitioner to quintessential professional, designed with the end user in mind.
Copper corrosivity has become a critical indicator of sulfur compounds present after the refining process. Prior to Copper Digital Detection Imaging (CuDDI), measuring corrosivity in petroleum presented a number of challenges. With no accurate standardized procedures in place, previous copper corrosion testing methods resulted in human error and bias due to manual visual assessments. CuDDI’s exclusive, patent pending copper corrosion test design takes the guesswork out of copper corrosion detection. Adhering to ASTM D130 and D1838, CuDDI precisely identifies corrosivity levels and eliminates operator bias through a 4-step automated vision algorithm and classification process. Its unique vision algorithm and light box records, calculates and displays accurate corrosivity ratings in a matter of seconds.
CuDDI’s simplified, breakthrough procedure provides improved ratings, corrosion testing methods and sample handling over current tests. A high-resolution camera with sophisticated optics provides higher precision machining and motors for the rotation of the copper strip. Using a corrosion detection range of 1a through 4C, outcomes are digitally recorded and seamlessly integrate with LIMS software. The results are not only a groundbreaking improvement on current laboratory procedures; they are the new standard for copper detection.
