Steel Digital LCD Hardness Testing Machine , Brinell / Rockwell / Vickers Hardness Tester
Main function and features
1. This machine with concise design, stable function, handy operation, which is adapted to fine
mechanical technique and photoelectric technology new type hardness tester
2. The outer shell of machine is formed of special founding onetime casted technique, stable structure,
it is not easy to be out of shape
3. It is automatic to test when the working platform lifting up to some height, then indicate the test result
directly
4. It can directly read the Brinell and Vickers hardness value by Omron encoder digital objective
5. It is equipped with 7 grades test forces, which can test the Brinell, Rockwell and Vickers three
hardness value, it can meet customers’ requirements
6. Built-in printer, it can print out the test result
7. It can connect to the computer, analyze, print the report by software.
Main Uses:
Chilled steel, surface hardening steel, hard alloy steel, cast iron, ferrous metal, all kinds of hardening
and tempering steel, harden thin plate, also adapted to soft metal, surface heat treatment and chemical
treatment etc.
