JER-210
Portable Surface Roughness Tester with Separate Probe
Suitable for on-site inspection of large workpieces and production lines, as well as field calibrations by testing, metrology, and commercial inspection departments—all without damaging the workpiece. Measurable surfaces include: flat surfaces, outer cylindrical surfaces, tapered surfaces, internal bores, grooves, curved surfaces, and other irregular geometries (when equipped with the appropriate sensor).
