Roughness Calibration Block Sets Square Wave 5 pcs RA 0.1,0.4,0.8,1.6,3.2μm Five Blocks Plates Multi-Engraved Lines Standard Roughness Calibration Sample for Surface Roughness Tester Gauge

Roughness Multi-Scratch Pattern | Calibration Block:◆Widely applicable for the calibration of readings on various domestic and imported roughness measuring instruments, including pocket-sized roughness testers, portable roughness testers, handheld roughness testers, and bench-top roughness testers.◆Glass-based surface roughness multi-scratch pattern gauge | Calibration block conforming to ISO 5436-1:2000.Calibration Standards of the Metrology Institute◆----High hardness glass substrate with no deformation◆----High surface precision◆----Resistant to scratches◆----Long service life◆----Fully Compliant with GB/T19067.1—2003 and ISO5436—1:2000 Standards◆----Minimal Influence from Stylus Radius Variations◆----Utilizes simulated sine profile grooves and triangular profile grooves, minimizing stylus radius variations and ensuring high calibration accuracIntroduction:◆Square Wave (Standard waveform with rectangular profile. Currently, nearly all domestically produced roughness testers are equipped with square wave standard blocks due to their low cost).◆RA=0.1~3.2μm(RA 0.1,0.4,0.8,1.6,3.2μm Five Blocks)◆Please note that A set of 5 Calibration Block in the package.
