Elcometer 125 Surface Comparator
 


Elcometer 125 Surface Comparator Comparators allow the estimation of surface roughness by both touch and sight.
  • Available in both Grit and Shot
  • Metric units only

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.
