Overview:The MHBS-3000 direct reading digital Brinell hardness tester is a newly developed and domestically advanced next-generation Brinell hardness tester. Applicable to the determination of Brinell hardness of black and non-ferrous metals. This machine adopts closed-loop sensor loading, electronic control system, photoelectric sensing and other systems, with a testing force of 10 levels. The touch screen operation is intuitive and simple, with the option to choose between testing methods and various hardness conversions. The data of various operation processes and test results can be displayed on the 5.6 screen, and the data of test results can be output through USB. The loading time is doubled compared to the past (8 seconds), greatly shortening the operation process. This machine is suitable for testing laboratories of various production and processing enterprises, colleges and universities, and research machinery.
Main functions:
The menu structure allows for the display of data on various operation processes and test results on the large LCD screen;
The experimental process is automated and easy to operate;
Equipped with hardness value conversion function, capable of judging the upper and lower tolerances of hardness;
Adopting closed-loop sensor loading and electronic control system loading, automatically compensating for experimental force;
High definition optical system and photoelectric sensing system for clearer and easier observation;
Encoder input of indentation diameter length D1 and D2 values to reduce human reading errors;
The data of the experimental results can be output through a printer;
The pressure head and objective lens automatically switch.
Application scope:
The Brinell hardness test uses a large testing force and a large indentation diameter, making it suitable for hardness testing of large grain metal materials, such as cast iron, non-ferrous metals and alloys, various annealed and quenched and tempered steels, especially for softer metals such as pure aluminum, lead, tin, etc.
