Elcometer 129 Rubert & Rugotest Surface Comparators

The Elcometer 129 Rubert & Rugotest Surface Comparators are precision reference tools used for visual and tactile comparison of surface roughness following abrasive blast cleaning. These comparators are especially valuable for field inspections where rapid assessment is required to ensure the surface meets preparation standards prior to coating.

There are two primary models in this series:

Elcometer 129 Rubert – available as individual comparators for grit or shot blasted surfaces.
Elcometer 129 Rugotest – combines both shot and grit profiles on a single block.

Each comparator displays six roughness values, presented both in "classes" and actual roughness averages, which makes profile evaluation more intuitive and precise. These tools are available in metric units only and are manufactured in accordance with AS 3894.5 standard.

Choose the Elcometer 129 series for instant, reliable, and repeatable surface roughness verification in the field. Whether you need to inspect grit or shot blasted finishes, or both in one compact tool, this comparator series offers a professional solution trusted worldwide. Contact us today for more details!
