    • The 2.4-inch color graphic LCD provides excellent readability and an intuitive display that is easy to use. The LCD also includes a back light for improved visibility in dark environments.
    • The Surftest SJ-210 can be easily operated using the buttons on the front of the unit and under the sliding cover. 
    • Up to 10 measurement conditions and one measured profile can be stored in the internal memory. 
    • An optional memory card can be used as an extended memory to store large quantities of measured profiles and conditions. 
    • Access to each feature can be password protected, which prevents unintended operations and allows you to protect your settings. 
    • The display interface supports 16 languages, which can be freely switched. 
    • An alarm warns you when the cumulative measurement distance exceeds a preset limit. 
    • The Surftest SJ-210 complies with the following standards: JIS (JIS-B0601-2001, JIS-B0601-1994, JIS B0601-1982), VDA, ISO-1997, and ANSI
    • In addition to calculation results, the Surftest SJ-210 can display sectional calculation results and assessed profiles, load curves, and amplitude distribution curves.
