for Testex Replica Tape

The Testex Digital Micrometer is a purpose-built digital thickness gage designed for accurate measurement of Testex Press-O-Film Replica Tape used in surface profile inspection. It simplifies the process of measuring blasted steel surfaces by automatically accounting for the replica tape backing thickness and applying the appropriate conversion factors when a tape grade is selected.

Why is it important?

Surface profile measurement is a critical step in protective coating applications. A properly prepared surface helps ensure coating adhesion, long-term coating performance, and compliance with project specifications and international inspection standards. By measuring the compressed replica tape after it has been burnished onto the surface, the Testex Digital Micrometer provides a fast and reliable indication of the peak-to-valley surface profile height.

Typical Application

The instrument is ideal for use in coating inspection, abrasive blasting control, corrosion protection, marine and offshore maintenance, bridge and infrastructure projects, pipeline inspection, industrial fabrication, and quality control applications where surface preparation must be verified before coating application.

How does it work?

Checkline's Testex Press-O-Film Replica Tape consists of a compressible foam layer attached to an incompressible 50 µm (2 mils) polyester backing. When the tape is pressed against a roughened steel surface, the foam forms an impression of the surface profile. The burnished tape is then placed between the anvils of the Testex Digital Micrometer, which measures the thickness and displays the corrected surface profile value.
