เครื่องวัดความเรียบ

Surftest SJ-210 portable surface roughness tester. Numerous innovative features combined with high accuracy and a competitive price makes this instrument the new class leader.

The Surftest SJ-210’s large, 2.4-in. color LCD display includes backlighting, over-size fonts, and the unique ability to reorient screen content to be read vertically or horizontally, left- and right-handed. Color tolerance judgments, evaluation curves and all data can be displayed in one of 16 languages. Self-timed measurement and optional foot switch facilitate smooth, consistent operation. Up to 10 measurement conditions can be registered and the 10 most recent trace results are stored automatically. The SJ-210 employs a micro-SD card for storage of up to 10,000 results and support of screen capture. Both USB and RS-232C connectivity is supported. Security is managed via a password lock.

Standard Drive Unit				Transverse tracing Drive Unit				Retractable Drive Unit
• Popular standard drive unit		• Best suited for measurement of narrow, shrouded workpiece features such as crankshaft, EDM parts, etc.		• The detector is in the rectracted position at rest so it is immune from damage when inserted into a feature whose profile cannot be easily seen, such as a blind hole, etc.

> Drive unit detached from Display unit
