HBRVS-187.5 Digital Brinell Rockwell Vickers Hardness Tester


HBRVS-187.5 Digital Brinell Rockwell Vickers Hardness Tester has novel appearance, complete functions, convenient operation, clear and intuitive display, and stable performance. It is a high-tech product integrating light, machine and electricity, and can be used in Brinell, Rockwell, Vickers three methods test, multi-functions hardness tester with multi-level test force, can meet a variety of hardness testing needs.


1. Using 8-inch touch screen and high-speed ARM processor, intuitive display, friendly human-computer interaction, and easy operation;

2. The fuselage is made of high-quality cast iron by one-time casting, and the car paint treatment process is used to make the appearance round and beautiful;

3. The measuring device adopts a grating displacement sensor, which displays the results through the LCD screen, and can display and set the test scale, test force, indenter type, holding time, conversion unit, etc.;

4. It has three test methods of Brinell, Rockwell and Vickers, and multi-level test force, which can meet various hardness test requirements;

5. The electronic closed-loop control applies the test force, which fully realizes the automatic operation of automatic loading, holding and unloading of the test force;

6. The combination of high-definition measurement and observation objective lens, combined with the high-definition micrometer eyepiece with built-in length encoder, realizes one-key measurement of indentation diagonal, which greatly reduces human operation interference and reading errors;

7. The built-in test software can modify the hardness value of the machine;

8. Convenient control system, which can automatically convert the unit of the full hardness scale;

9. Built-in printer, and can output data through RS232 port.
