Strictly compliant with ASTM E140 & ISO 18265 standards. Convert HRC, HV, HB and 11+ scales with absolute confidence—even offline.
Designed for the workshop floor and the design lab. We cut out the noise and focus on accurate data.
Data sourced strictly from ASTM E140 and ISO 18265 tables. No unreliable algorithms or approximations.
Deep inside a factory or in a shielded lab? No problem. Hardness works completely locally on your device.
Exclusive feature: Estimate steel tensile strength (MPa) instantly based on Vickers hardness readings.
Also includes smart alerts for values "outside standard range" to ensure your engineering rigour.
