Description
Summary:
Small Loading Brinell hardness testing machine can reflect the overall performance of the materials, but cant be influenced by the sample organization and composition micro-segregation uneven, so it is a hardness test of high precision. It is widely used in metallurgy, forging, casting, without hardened steel and non-ferrous metals industries, laboratories, universities and scientific research units. It is the closed loop sensor loading, the electronic automatic loading system, has 10 levels test force. The machine has high precision, high repeatability and stability, easy operation.
Application Areas:
Suitable for the precision testing of parallel plane,
Stable and reliable for the curved surface testing .
Application Materials:
Measuring Brinell hardness of ferrous metals, non-ferrous metals and bearing alloys; soft metals, small and thin parts.
Features:
- 4 inches LCD display, Menu structure
- With Motorized turret function
● Automatic test process, easy to operate
● High-definition optical system, light source brightness can be adjusted by 20 levels.
● With hardness value conversion function, hardness up and down tolerance judgment.
● Diagonal length D 1 and D 2 encoder input to reduce manual reading error.
● The objective lens and the pressure head can automatically switch and locate accurately.
● Test results and data processing, can be output through the printer.
