Germany's pride, the world's Harley company, Roughness Master KNT-4058
World Standard Roughness Master KNT-4058
HALLE Corporation has achieved very difficult manufacturing that allows the same profile to be repeated at a cut-off length, resulting in the creation of stable roughness standard pieces. This roughness master is used by manufacturers of roughness measuring instruments and metrology institutions around the world. It is of A-class, the highest precision. Additionally, there is a B-class available, which has a larger guarantee of repeatability and is set at a slightly lower price.
basic information
KNT-4058 is available in three roughness levels: Level 1 KNT-4058/01A1 Ra = 0.2μm, Rz = 1.5μm, Level 2 KNT-4058/01A2 Ra = 0.5μm, Rz = 3μm, Level 3 KNT-4058/01A3 Ra = 1.5μm, Rz = 8.5μm. The manufacturing variation "S" is 3% Class A. The inspection certificate can be selected from the following three: PTB (German Federal Institute of Physics and Technology), DAkkS (German ISO17025 organization), Manufacturer: HALLE.

Applications/Examples of results
Many companies, including inspection agencies, measurement instrument manufacturers, and manufacturers of automobiles and printers, are already using it as a master. By using a reliable master, one can understand the measurement error and degradation level of the roughness measuring instrument being used, and since traceability is well established, it is optimal for inspections and quality control that are struggling with surface roughness evaluation. Recalibration takes time, so please consider this adequately when making your request.
