Specifications
Measurement Parameters
The Mitutoyo 178-581-11E Skidded, Skidless Surface Roughness Tester measures a wide range of parameters to accurately evaluate the surface finish of a material. It can measure roughness, waviness, and primary profile parameters, including Ra, Rz, Rq, Rt, and Rp.
Measurement Range
This tester has a measurement range of 0.005 – 16μm (0.0002 – 630μin) for skidded measurement and 0.080 – 800μm (3.15 – 31500μin) for skidless measurement. This wide measurement range makes it suitable for measuring the surface roughness of a variety of materials, from very smooth surfaces to highly textured surfaces.
Probe Type
The Mitutoyo 178-581-11E Skidded, Skidless Surface Roughness Tester comes with a skidded probe and a skidless probe. The skidded probe is designed to measure roughness parameters, while the skidless probe is designed to measure both roughness and waviness parameters.
Stylus
The stylus of this tester is made of diamond, which is a highly durable and wear-resistant material. The diamond stylus is designed to provide accurate and repeatable results, even when measuring highly textured surfaces. The stylus tip radius is 2μm (0.08mil), which ensures accurate measurement of small features on the surface of a material.
Measurement Force
The measurement force of the Mitutoyo 178-581-11E Skidded, Skidless Surface Roughness Tester is 0.75mN (0.0765gf) for skidded measurement and 4mN (0.408gf) for skidless measurement. This measurement force is sufficient to provide accurate results while minimizing damage to the surface of the material being measured.
Drive Unit
The drive unit of this tester is designed to provide smooth and precise movement of the stylus across the surface of the material being measured. The drive unit is equipped with a high-precision linear encoder that ensures accurate positioning of the stylus.
Measurement Display
The Mitutoyo 178-581-11E Skidded, Skidless Surface Roughness Tester is equipped with a large, easy-to-read LCD display that shows the measurement results in real-time. The display shows the measured value, the measurement unit, and the measurement mode.
Measurement Standards
This tester is compliant with ISO 3274, JIS B 0601-2001, and ANSI B46.1-2009 standards, ensuring that the measurement results are accurate and reliable. These standards specify the measurement parameters, measurement conditions, and calibration procedures for surface roughness measurement instruments.
Conclusion
The Mitutoyo 178-581-11E Skidded, Skidless Surface Roughness Tester is a highly accurate and versatile instrument that provides precise and repeatable results. Its wide measurement range, diamond stylus, and compliant measurement standards make it suitable for measuring the surface roughness of a variety of materials.
