Pocket Size Surface Roughness Tester Follow ISO DIN Measurement Method¹

Product Description Pocket Size Surface Roughness Tester Follow ISO DIN Measurement MethodAdvanced Portable Surface Roughness Tester SR-300T is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.Application:Portable Surface Roughness Tester SR-300T allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy workpiece, assembly line on site. The SR-300T is a Non Destructive Testing instrument, damage won't caused to testing piece.The stylus drive unit can be stored within the main unit for standard measurement, or separated from the display unit by using the supplied cable which allows more flexible measurement in any orientation. The driver can be separated and reattached in one simple stepTechnical Specification:Measurement RangeThe Z axis (vertical)±80μm/±160 μm(enhanced model)The X axis (Transverse)17.5mmResolutionThe Z axis (vertical)0.01μm/±20μm0.02μm/±40μm0.04μm/±80μm0.08μm/±160μmMeasurement itemParameterRa, Rz, Rq, Rt, Rp, Rv, R3z, R3y, Rz(JIS), Rs, Rsk, Rsm, Rku, Rmr, Ry(JIS), Rmax, RPc, Rk, Rpk, Rvk, Mr1, Mr2StandardISO, ANSI, DIN, JISGraphicBearing area curve, Roughness profile, Primary profileFilterRC, PC-RC, Gauss, D-PThe sampling length(lr)0.25, 0.8, 2.5mmAssessment length(ln)Ln= lr×n    n=1~5SensorMeasuring methodskiddedStylus tipDiamond, 90 cone angle, 5μmRForce<4mNSkid parthard alloy, skid radius of curvature: 40mmTraversing speedlr=0.25,   Vt=0.135mm/slr=0.8,    Vt=0. 5mm/slr=2. 5,    Vt=1mm/sReturn      Vt=1mm/sAccuracyLess than ±10%RepeatabilityLess than 6%Power supplyBuilt-in Lithium ion battery, Charger :DC5V,3200mAOutline dimension Main unit: 52*55*158mm   drive: 23*27*115mmWeight(main unit)Around 400gworking EnvironmentTemperature: - 20oC ~  40oCHumidity: < 90% RHStore and TransportationTemperature: - 40oC  ~   60oCHumidity: < 90% RHMeasuring Range:ParameterRangeRa,Rq0.005μm  ~  30μmRz,R3z,Ry,Rt,Rp,Rm0.02μm  ~  320μmSk0  ~  100%S,Sm1mmtp0 ~ 100%Standard packing list:SR-300T main unit1 pieceSensor Drive1 pieceStandard Sensor1 pieceCalibration block and bracket1 pieceHeight adapter1 piecePower adapter 1 pieceManual book1 piece
