The Surftest SJ-210 is a user-friendly

surfaceroughness measurement

instrument designed as a handheld tool

that can becarried with you and used

on-site.

Easy to use

2.4-inch color graphic LCD with backlight

The color LCD provides excellent readability and an intuitive

display that's easy to negotiate.

The LCD also includes a backlight for improved visibility in dark

environments.

Simple key layout

The Surftest SJ-210 can be operated easily using the keys on the

front of the unit and under the sliding cover.

Highly functional

Advanced data storage capabilities

Up to 10 measurement conditions and one measured profile

can be stored in the internal memory.

Optional memory card

An optional memory card can be used as an extended memory

to store large quantities of measured profiles and conditions.

Password protection

Access to each feature can be password-protected,

which prevents unintended operations and allows you

to protect your settings.

Multilingual support

The display interface supports 16 languages, which can be freely

switched.

Stylus alarm (patent pending in Japan)

An alarm warns you when the cumulative measurement

distance exceeds a preset limit.

Extensive analysis and display features

Complies with many industry standards

The Surftest SJ-210 complies with the following standards: JIS

(JIS-B0601- 2001, JIS-B0601-1994, JIS B0601-1982), VDA,

ISO-1997, and ANSI.

Displays assessed profiles and graphical data

In addition to calculation results, the Surftest SJ-210 can

display sectional calculation results and assessed profiles, load

curves, and amplitude distribution curves.
