Overview:The MHBE-3000 touch screen electronic Brinell hardness tester is suitable for measuring the Brinell hardness of black and non-ferrous metals. This machine adopts a closed-loop sensor loading and electronic control system, with a testing force of 10 levels. This machine has the characteristics of high precision, high repeatability, stability, and easy operation. The loading time has doubled compared to the past (within 8 seconds), greatly shortening the operation process. Input d1d2 on the screen to obtain the hardness value.
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;
Input the values of indentation diameter length D1 and D2 to reduce human reading errors;
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.
