SJ-210 – Portable Surface Roughness Tester

The Surftest SJ-210 is a surface roughness measuring instrument that provides measurements in both the X and Y axes.

Product Features 

The Surftest SJ-210 features a 2.4-inch color LCD display for improved visibility, readability, and usability in dark environments.

Clearly defined operation keys are located on the front of the unit, accessible under a sliding cover.

Internal memory can store up to 10 measurement conditions and one measured profile.

Optional memory card support allows for storage of large quantities of measured profiles and conditions.

Technical Specifications

Password protection ensures instrument settings are secure and prevents unintended operations.

The display interface supports 16 interchangeable languages for user convenience.

The LCD display mode can be freely switched between portrait and landscape orientations, as well as left-hand or right-hand directions.

Compliant with various standards including JIS, VDA, ISO, and ANSI.


Technical Data


The Surftest SJ-210 surface roughness measuring instrument features a built-in color LCD display that allows users to view surface roughness waveforms. The display provides sectional calculation results, assessed profiles, load curves, and amplitude distribution curves, along with calculation results. 

This versatile instrument can perform measurements in any orientation, including vertical and upside-down positions. Optional accessories, like the height gage adapter, enable efficient measurements in different situations and setups.
