Thickness logging with D-50

The Sitescan D-50 offers end users an entry-level broadband flaw detector in the popular and portable casing of the renowned D-Series product line. The T-log feature of the Sitescan D-50 allows users to record multiple thickness measurements of a corroded area. The data can be saved and then exported into a CSV file format. A more advanced assessment based on the API 579 standard can then be performed. Other advanced features, such as an envelope, T-min and echo-to-echo measurements are available with this equipment.
