TQCSHEEN LD2065 Testex Replica Tape, Press O-film
Replica tape for measuring blasted surface profiles. By placing the Tqc replica tape on the surface and rubbing over it,the Rt (total roughness) or peak-to-valley height of the profile can be taken and then measured with a film thickness meter.
- TQC Replica tape consists of a layer of compressible foam affixed to an incompressible polyester substrate.
- When pressed against a roughened/grit blasted (steel) surface, the foam collapses acquiring an impression of the surface.
- Placing the compressed tape between the anvils of the SP1570 micro-metric thickness gage, and subtracting the contribution of the incompressible substrate (50 micrometers or 0.002 inches), gives a measure of the surface profile.
One box of Testex contains tape for 50 measurements.
