SRT-6210 Digital Portable Surface Roughness Tester - Measure Ra, Rz, Rq, Rt Parameters - Ideal for Metalworking, Automotive & Quality Control Inspections

Introduction: This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement parameters.When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. Specification: Display:4 digits,10 mm LCD,with blue backlight Parameters:Ra,Rz,Rq,Rt Measuring Range Ra,Rq:0.005-16.00um/0.020-629.9uinch Rz,Rt:0.020-160.0um/0.078-6299uinch Accuracy:≤10% Fluctuation of display value:≤6% Sensor: Test Principle: Inductance type Radius of Probe Pin:5um Material of Probe Pin:Diamond Dynamo-measurement of Probe: 4mN(0.4gf) Probe Angle:90 Vertical Radius of Guiding Head:48mm Maximum driving stroke:17.5mm/0.7inch Cutoff length (l):0.25mm/0.8mm/ 2.5mm optional Evaluation length:5l Driving speed: sampling length=0.25mm Vt=0.135mm/s sampling length= 0.8mm Vt=0.5mm/s sampling length=2.5mm Vt=1mm/s returning Vt=1mm/s Profile digital filter Filtered Profile:RC Filtered Profile:PC-RC Filtered Profile:Gauss Non-Filtered Profile:DP Resolution: .001um if reading less than 10um 0.01um if reading more than 10um but less than 100um 0.1um if reading more than 100um Evaluation length:5 cut-off
