Product Description

Elcometer 129 Rubert & Rugotest Surface Comparators

The Elcometer 129 Rubert & Rugotest Surface Comparators allow the estimation of surface roughness, by both touch and sight.Elcometer 129 Rubert Comparators are available in two models :

  • The Elcometer 129 Rubert – 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

The Elcometer 129 can be used in accordance with:

  • AS 3894.5

Test Method

Elcometer 129 Rubert & Rugotest Surface Comparators – Test Method

Test Method – ASTM D4417 Method A

In Summary, this test method requires that the appropriate comparator is selected and compared with the surface by sight – with or without magnification, or touch.

The closest match to the actual surface indicates the surface roughness.

Comparisons should be made at an agreed series of locations, which characterize the surface.
