Testex Replica Tape
Whereas comparators allow the
estimation of surface roughness by both
touch and sight, the Testex Tape allows the user to measure
the peak to valley height of the profile
and record it.
Testex Tape consists of
foam with a non-compressible backing.
The foam side is rubbed onto a surface
providing a permanent mould of the
profile.
The Thickness Gauge is
then used to measure the peak-to-valley
height of a surface profile formed in
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.
