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

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:◆Simulated sine wave (wave waveform, less affected by changes in the radius of the measuring needle, high precision. This sample is the first choice in the new standard. Imported roughness meters are equipped with simulated sine waves, which are slightly more expensive but have higher precision).◆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.
