Elcometer 122 Testex^® Tape consists of foam with a non-compressible backing. The foam side is rubbed into the surface providing a permanent mould of the peak-to-valley profile. The profile of the surface can then be measured using the Elcometer 124 Thickness Gauge.

Elcometer 122 Testex^® Replica Tape is available in four profile ranges. It is important that the tape grade chosen is reflective of the profile being measured.

• For surface profiles between 12 & 25µm (0.5 & 1.0mils): Coarse Minus Tape
• For surface profiles between 20 & 38µm (0.8 & 1.5mils): Coarse Tape
• For surface profiles between 38 & 64µm (1.5 & 2.5mils): Average of Coarse and X-Coarse Tape
• For surface profiles between 64 & 115µm (2.5 & 4.5mils): X-Coarse Tape
• For surface profiles greater than 115µm (4.5mils): X-Coarse Plus Tape

There are 50 tests in each Replica Tape roll.
