Portable roughness tester

Portable roughness testers are metrology instruments designed to measure the surface condition and roughness of industrial parts directly on the production line or in the workshop. Compact and easy to carry, they allow quick inspection of machined surface quality without having to move parts to a measurement laboratory. These devices generally use a high-precision tactile probe that moves across the surface of the part to analyze different roughness parameters such as Ra, Rz, or Rmax, which are essential for verifying the conformity of mechanical surfaces. Portable roughness testers are equipped with an intuitive touchscreen, an integrated analysis system, and can measure dozens of roughness parameters, providing performance close to laboratory equipment while remaining mobile.
