Barcol Hardness Tester

The Barcol Impressor is mainly applied in quick hardness testing of aluminum, aluminum alloy and glass fiber reinforced plastics. It has easy operation and wide test range. With single hand operation, the test can be finished as long as touching only one side of specimen. The Barcol hardness value can be converted to HW, HB,HR and HV according to the appendix hardness conversion table.

There are three models in the range:
