Detail Elcometer 7061 MarSurf PS1 Surface Roughness Tester

MarSurf PS1 Surface Roughness Tester | Elcometer 7061
SKU: K7061M001

Product Description

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 surface roughess 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.
