Digital Barcol Hardness Tester TM937-1s
TMTeck Digital Barcol Hardness Tester is a portable indentation hardness tester developed on base of Barcol impressor.
Standard Conformance
Comply to standard JJG610-2013 and ASTM B648-10(2015).
Theory
The theory of digital Barcol hardness tester is to apply with specific shape steel indentor to press in workpieces surface through test force caused by load spring. When supporting foot is closed to the workpieces surface, measure the extension length of the indentor.
Application
Digital Barcol Hardness Tester is applied to test the hardness of Aluminum, Aluminum alloys, Fiber Reinforced Plastics and rigid plastics etc. wide valid testing range equivalent to Brinell hardness 25-150HBW.
