Surface Roughness
Machined

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.

TR100 Portable Roughness Tester

TR100 Portable Roughness Tester

Hand-held digital display of measurement in Ra(ISO) or Rz(DIN). Measures on most surfaces with a flat axis (outside and inside of cylinders and cones), grooves and recessions greater than 80 x 30mm.

Elcometer 129 Rubert & Rugotest Surface Comparators

Elcometer 129 Rubert & Rugotest Surface Comparators

Similar to the Elcometer 125, the Elcometer 129 roughness comparators are available in two models: The Elcometer 129 Rubert is available in grit and shot versions whereas the Elcometer 129 Rugotest includes the shot and grit profiles on the same block. Conforms to ASTM

Elcometer 147 Cambridge Weld Gauge

Elcometer 147 Cambridge Weld Gauge

The Elcometer 147 Cambridge Weld Gauge measures many aspects of welds both in metric and imperial units. It measures : Angle of preparation 0 to 60º, Misalignment (high – low), Fillet weld throat size, Fillet weld length, Excess weld metal (capping size), Depth of undercut, Depth of pitting, General linear measurements up to 60mm, 2mm edge roundness test

Elcometer 7060 SURFTEST SJ-201 Roughness Tester

Elcometer 7060 SURFTEST SJ-201 Roughness Tester

Designed for measurement of machined profiles, these gauges measure the profile by the use of a motorised travel of the sensor which passes over the surface to be tested. A range of different roughness values can be displayed on the LCD.

Elcometer 7060/4 SURFTEST SJ-301 Roughness Tester

Elcometer 7060/4 SURFTEST SJ-301 Roughness Tester

The new generation, high performance roughness unit, working on the same principle as the Elcometer 7060 but fitted with a built-in printer and a large LCD touch panel for numeric/graphic display and settings.
