Testex roughness testing instrument
According to ISO 8503-5 / ASTM D4417 / NACE / SSPC
This measuring gage is used for the determination of roughness like blasted surfaces.
The replica film is placed at the surface and is rubbed on with light pressure. The profile is now copied onto the film and can be measured by the help of the micrometer clock. The result is comparable with the roughness parameter Rz.
