This surface roughness tester is ideal for proper and effective preparation of a surface profile prior to coating is essential.
Making sure that the correct roughness – or surface profile – has been generated is essential. If the profile is too low, the adhesion of the coating to the surface will be reduced. Too high and there is the danger that the profile peaks will remain uncoated – allowing rust spots to occur.
The Elcometer 129 Surface Comparators are available in two models:
- Elcometer 129 Rubert – available in grit and shot versions.
- Elcometer 129 Rugotest – shot and grit profiles on the same block.
Roughness is displayed in both “classes” and “roughness averages” for easier identification and are available in Metric units.
- 6 Roughness Values per Comparator
