Testex CX Complete "Press-O-Film" Kit Includes 1 roll each of COARSE and X-COARSE Press-O-Film Tape, Inch Dial Thickness Gage, Training Surface, Burnishing Tool, and Instruction Book.

Testex is the manufacturer of Press-O-Film replica tape. Press-O-Film provides inspectors and researchers a simple way to obtain an impression of a surface. Testex replica tape can be used with a Testex gage to measure the surface roughness ("profile") of blast-cleaned steel in the roughness range 0.8 to 4.5 mils (or 20 to 115 micrometers). Because inspectors, as a rule, have a target profile in mind. it is always best to start measurements with the grade of tape that has the target profile closest to the center of it's range.
