The Surftest SJ-210 is a user-friendly surface roughness measurement instrument designed as a handheld tool that can be carried with you and used on-site. The Surftest SJ-210 surface roughness measuring instrument allows users to view surface roughness waveforms on the built-in, color LCD display. The display provides operators with sectional calculation results, assessed profiles, load curves, and amplitude distribution curves in addition to calculation results. This instrument is able to perform measurements in any orientation, including both vertical and upside-down. Optional accessories, such as a height gage adapter, efficiently perform measurements in various situations and setups.
