Automatic digital hardness tester for Brinell test method in compliance with ASTM E10 and ISO 6506 hardness standards. Integral 1 is a top level bench hardness tester for fully automatic Brinell test cycles. It is entirely motorized with an automatic turret with indenter and magnification lenses for Brinell indent autoreading after indentation. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Exact hardness result on the first test and R&R data at the top of his class, absolute accuracy (better than 0.5 %) in every condition. Integral 1 has a large fixed base and a motorized head with long vertical stroke. Hardness testing on every metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys.
