Surface Roughness Testers

Surface roughness testers quantify the fine texture of a machined or prepared surface, reporting parameters such as Ra and Rz defined under ISO 21920 (formerly ISO 4287). Portable stylus instruments suit shop-floor and incoming-inspection checks, while profile gauges and replica-tape readers like the PosiTector SPG and RTR capture the peak-to-valley profile of a blast-cleaned surface ahead of coating.
