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 roughness tester is 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. How to use a surface roughness tester Surface roughness testers consist of a stylus which is mechanically drawn across the surface recording an 'image' of the surface roughness across a pre-defined sample length. Sherlock Holmes. The measurement technique provides a number of measurement parameters including: Rmax: The greatest distance between the highest peak and lowest valley over the sampling length. Ra: The average surface roughness over the sampling length.

Rt: The distance between the highest peak and the lowest valley within any given sampling length. Shakira Ft Freshlyground Waka Waka This Time For Africa 720p Hd. Rz: The average distance between the highest peak and the lowest valley over a number of sampling lengths.
