In protective coating applications there is a requirement to measure surface roughness. Measurements of Surface Roughness are expressed in terms of Ra, Rz or Tp. These values include peak-to-valley profile measurement in combination with an assessment of the frequency of peaks within the sample area.
The Elcometer 147 Cambridge Weld Gauge measures many aspects of welds both in metric and imperial units and includes: 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
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 … Read More
The TR3110 Portable Roughness Tester (previously the TR110) is the latest instrument combining electronics and probe in an Integral Unit. It is widely used to test various metal and non-metal processing surfaces. It determines both roughness parameters Ra and Rz within a wide measuring range. The piezo-electric pich-up stylus with diamond tip assures a very reliable measurement within tolerances conform with ISO class 3. Roughness parameter Ra conforms to ISO and Rz conform to ISO and DIN
