934-1 Barco • A portable indentation hardness tester. • Single hand operation, no operating experience required, can test any workpiece which is reachable in any site.Wide valid testing range equivalent to Brinell harAdness 25-150HBW. 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. No supporting required. Can test from only one side of the workpiece. No need to move or support the workpiece. Used to test super large and thick worpieces and assembly parts. • Easy conversion. The test results can be converted to HB, HR, HV and HW easily through conversion table. • Comply to standard ASTM B648-2000. Technical Para m eters • Barcol Impressor is mainly applied to test Aluminum and Aluminum alloys. Webster is used to test Aluminum alloy extrusions, sheet and tubings. Barcol Impressor is suitable to test pure Aluminum, soft Aluminum alloys, super thick Aluminum alloys. Aluminum alloys bars and assembled Aluminum alloys parts (e.g. al-alloy door &window, scaling ladder etc. Relevant StandardlASTM B648 (Test Method for Indentation Hardness of Aluminum Alloys by Means of a Barcol Impressor) • Barcol Impressor is also used to test Fiber Reinforced Plastics and rigid plastics etc. Relevant Standard: ASTM D2583-07 (Test Method for Indentation Hardness of Rigid Plastics by Means of a Barcol Impressor) • The improved model of i Barcol Impressor is available to test softer plastics, very soft metals rubber and leather etc. Tester Spare indenters (2 pcs) High value Standard hardness block (2 pcs) Low value Standard hardness block (2 pcs) Calibration wrench Supporting foot Carrying case
