Mitutoyo Surftest 178-573-01E Series SJ-310R Portable Surface Roughness Tester, 0.75mN type Retractable type

Surftest SJ-310 Portable Surface Roughness Tester <br>A portable surface roughness tester able to operate independently of mains power and make measurements on almost any part of a workpiece of practically any size. <br>The large 5.7” color LCD with touch-screen functionality improves operability and provides high visibility.<br> Statistical analysis of up to 3 parameters from 300 samples can be performed showing average, standard deviation, max, min, pass rate and histogram. <br>Up to ten measurement setups, along with stored data, can be displayed and printed out on the built-in thermal printer, or stored in the built-in memory. <br>The Micro-SD card (optional) is supported to enable huge storage of measurement values, setups and statistical data, or auto save of the last 10 sets of measurement data. <br>The total measurement and sectional measurement results can be displayed as well as BAC/ADC curves. USB, Digimatic SPC output, RS-232C and external software connectivity is supported. <br>Security is managed via a password lock to eliminate error due to accidental resetting. Cissoidal calculation mode is supported in which one measurement can evaluate two different parameters.
