Digital Barcol Hardness Tester TM937-1s
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.

Features
- Single hand operation, easy to take, die-casting alloy shell, comfortable to hold.
- Digital display, more directly reading; Low-configuration can directly display Barcol hardness reading results; High-Configuration can converted Barcol hardness to HW, HV, HBW and HRE easily through conversion button.
- Easily to change indenter; when testing full scale, if it does not point at 100HBa, just to press the full-scale adjustment button is ok, solve the problem on hard full-scale calibration of Barcol impressor.
- External calibration mode, after finishing full-scale calibration, no need to take off the shell, only to adjust the screw reserved on the instrument, then can adjust the hardness value.
