Elcometer 122 Testex Replica Tape
- Replica tape is used to measure the profile of the substrate prior to coating
- Available in a range of tape grades for greater accuracy
- Used in conjunction with the Elcometer 124 Thickness Gauge
Whereas comparators allow the estimation of surface roughness by both touch and sight, the Elcometer 122 Testex Tape allows the user to measure the peak to valley height of the profile and record it.
Elcometer 122 Testex Tape consists of foam with a non-compressible backing. The foam side is rubbed into the surface providing a permanent mold of the peak-to-valley profile, which can then be measured using the Elcometer 124 Thickness Gauge.
Elcometer 122 Testex Tape is available in four profile ranges. It is important that the tape grade chosen is reflective of the profile being measured, as using tape grade below the actual value may provide a "false" reading.
There are 50 tests in each roll.
