Testex Press O Film Replica Tape consists of a layer of compressible foam affixed to an incompressible polyester substrate of highly uniform thickness. When pressed against a roughened steel surface, the foam collapses and forms an impression of the surface. Placing the compressed Testex tape between the anvils of a micrometric thickness gage such as the PosiTector RTR H Replica Tape Reader and subtracting the contribution of the incompressible substrate gives a measure of the surface profile.
Optical Grade XC Testex Replica Tape available — provides higher quality SDF surface data files than conventional replica tape (for use with PosiTector RTR 3D models).
Each roll of Testex Tape includes 50 pieces (Impressions).
