Testex Profile Tape

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 mould of the profile. The Elcometer 124 Thickness Gauge is then used to measure the peak-to-valley height of a surface profile formed in Elcometer 122 Testex Tape.


The Testex Tape range is available in four profile ranges. It is important that the tape grade chosen is reflective of the profile under measurement.
