A range of comparators for inspection on shot, grit & sand blasted surfaces.
Surface comparators are used to compare freshly blasted profiles to pre-defined profiles. The comparators are available as grit, shot or sand and comparisons can be made visually or by touch. This method is ideal for providing a very quick guide to the profile.
These extremely durable comparators allow the estimation of surface roughness of either grit or shot blasted surfaces.
Using the Elcometer 125 surface comparators as a reference the blasted profile can be compared to the four reference profile grades in each comparator.
The Elcometer 127 Sand Surface Comparator is supplied with 5 profile grades ranging from 0.5 - 4.0 mils.
Designed for use with the Elcometer 127 illuminated magnifier, this comparator has a hole in the center allowing for clear visual comparisons to be made.
The Elcometer 127 Grit Surface Comparator is supplied with 5 profile grades ranging from 1.5 - 5.5 mils.
Designed for use with the Elcometer 127 illuminated magnifier, this comparator has a hole in the center allowing for clear visual comparisons to be made.
The Elcometer 127 Shot Surface Comparator is supplied with 5 profile grades ranging from 2.0 - 5.5 mils.
Designed for use with the Elcometer 127 illuminated magnifier, this comparator has a hole in the center allowing for clear visual comparisons to be made.
The NACE Surface Weld Comparator with NACE written standard SP0178provides for the first time, a means of comparing the quality of welds prior to coating application.
Made from durable T Grade ABS plastic, the comparator comprises of 14 different examples of actual welds, allowing a thorough evaluation to be completed.
