The Barcol Impressor is an indentation hardness tester . The operation is easy , quick and almost non-destructive . The test is as simple as one press . It is a convenient tool for testing the hardness of aluminum , aluminum alloys and fiber reinforced plastics , which conforms to American Standard ASTM B648 .
Barcol Hardness Tester is mainly used to test the hardness of aluminum and aluminum alloys , to test the hardness of other soft metals and glass fibre reinforced plastic products . It can also be used to test the hardness of extra large , extra wide , extra thick work pieces , and to test the hardness of boards , belt materials , section materials , forgings and castings etc .
Barcol Hardness Tester is commonly used as supplement of Webster Hardness Testers . It is usually used when test the hardness of pure aluminum , low hard aluminum alloys and extra large , extra thick materials .
1 . Barcol Impressor is a portable indentation hardness tester .
2 . Single hand operation , operating experience required can test any operating experience whitch is reachable in any site
3 . Wide valid testing range equivalent to Brinell hardness 25-150HBW , used to test the hardness of all kinds of aluminum from very soft aluminum to very hard alloys .
4 . Barcol Impressor has a wide range of application . Model 934-1 can be used to test aluminum and aluminum alloys , copper and copper alloys , glass fiber reinforced plastics , rigid plastics , etc . The improved type can be used to test lead , tin and other soft metal , and flexible plastics , rubber , felt , leather , and so on .
5 . With 100 scales , our Barcol Impressor is of higher sensitivity than commonly used Webster hardness testers in aluminum alloy industry .
6 . It could finish the testing work on one side of the workpiece , without trouble of moving or supporting the workpiece . Due to this feature , the hardness tester can be used to test extra large , extra thick workpieces and assembly parts .
7 . By use of the conversion table , the test results can be easily converted to HB , HR , HV and HW .
8 . It meets the requirement of ASTM B648-2000 standard .
