SJ-310 Surface Roughness Tester

July 12, 2012

Mitutoyo America Corp. announces availability of the new Surftest SJ-310 surface roughness tester. Numerous innovative features combined with high accuracy and an economical price-point mean the Mitutoyo Surftest SJ-310 surface roughness tester provides real performance value.

With high accuracy (resolution of 0.002µm at a measurement range of 25µm), fast measurement speed (max. 0.75mm/s), a selection of 11 interchangeable detector tips and capabilities like gear tooth surface detection, the Surftest SJ-310's flexibility and throughput boost productivity.

The Surftest SJ-310's large, 5.7" color LCD with touch screen provides high visibility and enhanced operability. The instrument conforms to roughness standards JIS-B0601-2001, JIS-B0601-1994, JIS-B0601-1982, VDA, ISO-1997 and ANSI. After one measurement is performed, a waveform with scale and ruler options is displayed for detailed analysis, as well as the capability of calculations or evaluation under two different assessment conditions.

Additionally, the Surftest SJ-310 enables blueprint design code to be entered directly to simplify setting of complex evaluation conditions. Statistic measurements of up to 3 parameters each for as many as 300 samples can be performed providing average, standard deviation, max, min, pass rate and histogram. Up to ten measurement conditions and the stored data can be called up, displayed and printed using a built-in thermal printer. Also, the SJ-310 can store up to 10 measuring conditions in its on-board memory. The Surftest SJ-310 supports a micro-SD card (option) for storage of up to 10,000 text data, 500 measuring conditions, 1000 measuring data, 500 images (BMP), 500 statistic data or auto-save up to the last 10 measuring data. Total and sectional measurement results can be displayed in addition to evaluation and BAC/ADC curves.

The display unit supports Standard, S-Drive and R-Drive units. USB, Digimatic SPC output, RS-232C and external SW connectivity is also supported while available Mitutoyo software packages make it easy to integrate the SJ-310 into high-level network environments for enterprise-wide functionality. Security is managed via a password lock to restrict changes that could cause operation errors.
