T-Log for Thickness Surveys on the Wave, Masterscan and Sitescan Systems
One of the main applications of ultrasonic testing (UT) is thickness testing of plates and pipes to ascertain the remaining wall thickness and identify areas of corrosion/erosion.
A common method is to take individual ‘spot’ readings over a grid to cover large areas, e.g. 50 mm x 50 mm.

Thickness Inspections
Traditionally, the inspector would record each reading on a notepad, stopping every few readings to record them down or having an additional technician accompany them to record readings as they were called out. This is both time-consuming and expensive for the client to pay for extra personnel or extra time on the job.
The Sonatest Wave, Masterscan, Sitescan series, and Alphagage have thickness logging capabilities, which are referred to as T-Log. This feature allows users to create a grid and record inspection readings directly into the set. There is no need for an extra technician or to stop and manually record readings!

T-Log Colour Pallets
When using T-Log data, users can easily apply colour pallets to highlight low/out-of-tolerance readings for fast detection.
On the Wave, this can be shown during data acquisition; for our other systems, this can be applied in the post-analysis of the data using the UTLity PC software.

CSV Data Files
Both the Wave and the PC UTLity software can export data as an Excel CSV file, enabling users to use the data for remaining life calculations, to compare to previous data sets to determine a rate of corrosion, or to import it into reports.
