7 level of test forces, which can test several kinds of hardness.
Test force loading, dwell, unload adopts automatic shifting for
easy and fast operation.
It can show and set the present scale, test force, test indenter,
dwell time and hardness conversion.
Main Functions:
1, Support Brinell, Rockwell and Vickers three test modes;
2, Support hardness Conversion scales of different kinds of
hardness;
3, Test results can be saved for reviewing or be printed out,
4, Data statistics automatically calculate of maximum, minimum and
average value;
5, With RS232 interface for connecting to the computer.
Application Range:
Suitable for hardened and surface hardened steel, hard alloy steel,
casting parts, non-ferrous metals, various kinds of hardening and
tempering steel and tempered steel, carburized steel sheet, soft
metals, surface heat treating and chemical treating materials etc.

The diamond penetrator is used for testing materials such as
hardened steels and cemented carbides. The carbide ball
penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2
inch diameter, are used when testing materials such as steel-copper
alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell
testing (e.g., C and B scales) and Rockwell superficial testing
(e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low
numbers soft materials.
