Elcometer 129 Rubert & Rugotest Surface Comparators
Surface Profile
The proper and effective preparation of a surface prior to coating is essential. Making
sure that the correct roughness – or 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.
Elcometer 129 Rubert & Rugotest Surface Comparators
Comparators allow the estimation of surface roughness by both touch and sight.
The Elcometer 129 Rubert Comparators are available in two models:
The Elcometer 129 Robert available in Grit and Shot Versions
The Elcometer 129 Rugotest includes the shot and grit profiles on the same block
Available in metric units only
Roughness is displayed on both classes and groups for easier identification
Can be used in accordance with:
ASTM D 4417 Method A
