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 7061 Marsurf Ps1 Roughness Tester is a light weight and portable measuring solution for the range of surface roughness measurements required for compliance to International Standards. The unit is also suitable for assessing surface roughness conditions in a wide range of general industrial applications; particularly where the sample is too large to bring to the laboratory. • Multi-Lingual Display: All the required information is displayed on screen in a choice of 14 languages. • Flexible: Can be used in virtually any position; horizontally, vertically, upside down. A height adjustment accessory to accommodate various sample sizes is supplied with each gauge as standard. • Integrated Calibration Standard: No external calibration standard is required; provides greater ease of use. • Drive Unit: Can be rotated and moved longitudinally; enables the stylus pick-up to be moved to the calibrating position. The stylus pick-up is also protected for transport in this position. • Stylus pick-up with removable protection: 2μm (80μin) diamond stylus tip with a measuring force of 0.7 mN. Different stylus’ are available for various applications. The Elcometer 7061 Marsurf Ps1 Roughness Tester can be used in accordance with: • ISO 4287 • ISO 4287/1 • ASTM D4417 • ASME B46 • DIN 4768 • EN 10049 • JIS B 0601 Standards not in bold have been superceded but are still recognised in some industries.
