Twin Indenter Digital Micro Hardness Tester
● DM4 is precision micro Vickers hardness testing machines integrated the technology of optics, mechanics and
compute, and it is focus on the vickers testing under the small force, and mainly applicable to measure t he
hardness value of ferrous metals and non ferrous metals.
● Equipped with a LCD screen, the operation is more directly and clearly.
●Can display the measuring methods, testing force, indentation length, hardness value, dwell time of the testing
force as well as the number of measurement.
● Can save and revise the date, record the measuring results, compute the data, outputting the information with
the printer.
● Hardness conversion among 4 hardness scales, and linking to PC in RS 232 interface and cable.
● Adopt the design of double indenters, it equips with HV and HK indenter together, It is more suitable to measure
the hardness of IC thin sections, coatings , ply metals; Glass, ceramics, agate , precious stones and other brittle
and hard material.
