The Testex Gauge is used to measure the Testex Tape replica and determine the average maximum peak-to-valley height of the blasted profile.
Measurements are made by firstly zeroing the Gauge on -50µm (-2mils). This is to allow for the film backing. Place the replicated area between the anvils and gently lower the moveable anvil onto the film. The reading can now be taken, giving you the average peak-to-valley height of the blasted profile.
The Testex Gauge is supplied in an industrial foam-filled Carrying Case with Testex Tape X Coarse, Testex Tape Coarse and a Burnishing Tool.
