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 accurac

Introduction:
◆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.
