Testex Press O Film offers a unique replica technique with a simple snap gauge
Testex makes surface replicas easy to obtain and produces average maximum peak-to-valley readings that ensure optimum blasting effectiveness. Replicas can be retained for future needs.
The accuracy of Testex measurements is due to an innovative two-level film that can produce virtually exact replicas of the abrasive blasted surfaces. The film is available in three different thickness grades to cover the most common range of blasted profiles.
Measurements can be taken in internal pipe diameters and grooves, which are locations that are not accessible using conventional stylus devices.
Easy to use, remove the protective paper from the tape and place firmly on the blasted surface. Apply moderate pressure with the Burnishing Tool over the circular cut-out in the tape. Remove the tape. The replica is now ready for measurement using the Snap Gauge.
Complies with International Standards: ISO DIS 8503-3, BS 7079-C5,
ASTM D 4417-C and NACE RP 0287-95.
