The SURFPAK‑SJ system from Mitutoyo provides precise surface roughness measurements for a range of industrial applications. It supports multiple probe types (SJ‑400, SJ‑401, SJ‑402) and includes tilt‑compensation, statistical analysis, and RS‑232C communication.
The document lists measurement ranges, resolution, calibration standards, and accessory part numbers, helping users select the appropriate configuration and understand performance limits.
