The Barcol Impressor is a portable indentation hardness tester.

Single hand operation; no operating experience required; can test any work piece which is reachable in any site. Wide valid testing range equivalent to Brinell hardness 25-150 HBW.

It is used to test the hardness of all kinds of aluminum, from very soft aluminum to very hard aluminum alloys.

Extended application, model 934-1 is applied to test the hardness of aluminum, aluminum alloys, copper, copper alloys, fiber reinforced plastics and rigid plastics etc.

The improved model of it is available to test very soft metals such as lead and tin and other soft materials such as soft plastics, rubber, felt and leather etc.

High sensitivity, featured with 100 scales, much more sensitive than Webster hardness testers applied in aluminum alloys industry. It can test from only one side of the work piece.

No need to move or support the work piece.

It is used to test super large and thick work pieces and assembly parts.

Easy conversion, the test results can be converted to HB, HR, HV and HW easily through conversion table. Comply with standard ASTM B648-2000.
