Features and Benefits

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 performs measurements in various situations and setups.
  • Built-in 2.4-inch color graphic, back-lit LCD display provides excellent readability, improved visibility and is easy-to-use in dark environments
  • Operation keys are clearly defined on the front of the unit and under the sliding cover
  • Internal memory stores up to 10 measurement conditions and one measured profile
  • An optional memory card can be used to store large quantities of measured profiles and conditions
  • Password protection prevents unintended operations and protects instrument settings
  • The display interface supports 16 interchangeable languages
  • LCD display mode can be freely switched between portrait and landscape as well as left-hand or right –hand direction
  • The Surftest SJ-210 complies with the following standards: JIS (JIS-B0601-2001, JIS-B0601-1994, JIS B0601-1982), VDA, ISO-1997, and ANSI.
