L-3LSurftestPerforms brilliantly in many situations such as in the quality control room, on the factory oor and on the production line. Mitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.Surftest SJ-210SERIES 178 — On-site Surface Roughness TesterSPECIFICATIONSCompact type all-in-one surface roughness tester has evolved by meeting customer demands• Color LCD can display not only calculation results and measurement conditions, but also surface roughness waveforms. In addition, bigger character size contributes to visibility.• Supports a variety of roughness standards. Equipped with a variety of parameters and functions such as arbitrary length measurement. Facilitates the operation and settings using the buttons on the top and inside the openable cover of the main unit. Displays the result after a measurement when the measurement start button is pressed.• Built-in rechargeable battery allows measurement without the power supply.• Optional printer for SJ-210 allows the printing of calculation results and measured profiles.• Outputs the alarm display when the accumulated measurement distance exceeds the threshold level that is set. (Useful for maintaining a stylus-tip replacement policy.)• Three types of drive unit are available: Standard, Transverse tracing, and Retractable. Selectable depending on the workpiece.Refer to the Surftest SJ-210 series (Catalog No.E4388) for more details.Measurement start/stopSelection of roughness parametersSwitch ON/OFF/External outputDetailed measurementModel No.Standard drive unitRetractable drive unitTransverse tracing drive unitSJ-210(0.75mN type)SJ-210(4mN type)SJ-210(0.75mN type)SJ-210(4mN type)SJ-210(0.75mN type)SJ-210(4mN type)Code No.mm178-560-01178-560-02178-562-01178-562-02178-564-01178-564-02inch/mm178-561-01178-561-02178-563-01178-563-02178-565-01178-565-02Measuring rangeX axis16.0 mm5.6 mmDetectorRange360 µm(-200 µm to +160 µm)Range/Resolution360 µm / 0.02 µm, 100 µm / 0.006 µm, 25 µm / 0.002 µmMeasuring speedWhen measuring: 0.25mm/s, 0.5mm/s, 0.75mm/s When returning: 1mm/sMeasuring force/Stylus tip shapeDepends on the Code No.: 0.75mN/60º, 2µmR (when the Code No. ends with "-01")4mN/90º, 5µmR (when the Code No. ends with "-02")Skid force400mN or lessApplicable standardsJIS1982/ JIS1994/ JIS2001/ ISO1997/ ANSI/ VDAAssessed prolePrimary prole, Roughness prole, DF prole, Roughness motif proleParameterRa, Rc, Ry, Rz, Rq, Rt, Rmax*1, Rp, Rv, R3z, Rsk, Rku, Rc, RPc, Rsm, Rz1max*2, S, HSC, RzJIS*3, Rppi, R∆a, R∆q,Rlr, Rmr, Rmr(c), Rδc, Rk, Rpk, Rvk, Mr1, Mr2, A1, A2, Vo, Rpm, tp, Htp*4, R, Rx, AR, Possible CustomizeAnalysis graphBAC and ADC curvesFilterGaussian, 2CR75, PC75Cutoff valueλc0.08, 0.25, 0.8, 2.5 mmλs*52.5, 8 µmSampling length0.08, 0.25, 0.8, 2.5 mmNo. of sampling lengths×1,×2,×3,×4,×5,×6,×7,×8,×9,×10,arbitrary length (0.3 to16.0mm: 0.01mm interval)×1,×2,×3,×4,×5,×6,×7,×8,×9,×10,arbitrary length (0.3 to 5.6mm: 0.01mm interval)Dimensions of LCD display area36.7×48.9 mmDisplay languageSupports 16 languages (Japanese, English, German, French, Italian, Spanish, Portuguese, Dutch, Polish, Hungarian, Swedish, Czech, Simplied Chinese, Traditional Chinese, Korean, Turkish)Calculation result displayVertical display: 1 row/3 rows/TraceHorizontal display: 1 column/4 columns/Trace (Right/Left switching display is available.)Print functions *6Measurement condition / Calculation result / Calculation result per segment / Assessed prole / Material ratio curve / Prole height amplitude distribution curve / Environmental setting itemsExternal I/O functionsUSB I/F, Digimatic output, printer output, RS-232C I/F, foot switch I/FFunctionCustomizationDesired parameters can be selected for calculation and display.GO/NG judgment function*7Maximum value rule, 16% rule, mean value ruleStoring measurement conditionWhen the power is turned offStorageBuilt-in memory: Measurement condition (Up to 10)             Memory card (optional): 500 measurement conditions, 10000 measured proles, 500 display images, Text les (Measurement condition/Measurement data/Assessed prole/Material ratio curve/Prole height amplitude distribution curve)CalibrationAuto-calibration with the entry of numerical value /Average calibration with multiple measurement (Max. 5 times) is available.Power saving functionAuto sleep (settable in the range of 10 to 600 sec.) *8Power supplyBuilt-in battery (rechargeable Ni-MH battery) / AC adapter Charging time of the built-in battery: about 4 hours (may vary due to ambient temperature)Endurance: about 1000 measurements (differs slightly due to use conditions/environment)External dimensions(W×D×H)Calculation display unit52.1×65.8×160 mm (sliding cover closed, detector not mounted)Drive unit115×23×26 mm (excluding the detector)MassApprox. 500 g (Calculation display unit, Drive unit, Standard detector)Standard Accessories12BAA303 Connecting cable*9178-601 Roughness specimen12BAK699 Carrying case12BAK700 Calibration stageProtective sheet for displayAC adapter, Operation manualOne-sheet manual, Warranty card12BAA303 Connecting cable*9178-605 Roughness specimen12AAE643 Point-contact adapter12AAE644 V-type adapter12BAK699 Carrying case12BAK700 Calibration stageProtective sheet for the display, AC adapter, Operation manual, One-sheet manual, Warranty card*1: Calculation is available only when selecting the VDA, ANSI, or JIS 1982 standard.*2: Calculation is available only when selecting the ISO 1997 standard.*3: Calculation is available only when selecting the JIS 2001 standard.*4: Calculation is available only when selecting the ANSI standard.*5: Not available when selecting the JIS1982 standard*6: Please procure the printer for SJ-210 (Code No.: 178-421, Option) separately.
