Three Indenters Brinell Hardness Tester

XHB-3000Z Three indenters digital Brinell hardness tester adopts precise structure design and the load of test force is controlled by the sensor, which makes the whole structure compact and loading of test force stable and exact. It adopts an 8-inch HD color touch screen, which makes parameter settings and result display more intuitive, and operation more convenient. The instrument has three indenters and two objectives, just rotate the hand wheel to focus the sample and press start, the hardness tester will automatically select the corresponding indenter based on the test scale, and do loading, dwelling, unloading, and switching to the objective. After measuring through the eyepiece, the hardness value can be automatically calculated and displayed on the screen. This machine can be equipped with CCD image automatic measurement system to achieve one click automatic measurement of indentation.

Suitable for cast iron, steel products, nonferrous metals and soft alloys etc. Also suitable for some nonmetal materials such as rigid plastics and bakelite etc.

• The main body adopts cast iron structure which minimizes the deformation. The shell has undergone natural aging treatment for more than half a year, and its physical properties are stable.
• The structure realizes a 1:1 high-precision gravity sensing system combined with zero gap ball screw force control, using a 0.03 level force sensor to ensure precise and error free loading every time.
• After heat treatment, the hardness of the lifting screw reaches 35~40HRC, which is beneficial for the stability of the testing data at different heights during lifting.
• This instrument has 11 level of test force, 14 Brinell hardness test scales, suitable for different kinds of metal materials.
• With three indenters and two objectives, no need to change the indenters when testing different samples; with rigorous optical structure and high magnification, it makes the indentation observed clearly.
• According to the selected scale, the indenters and objectives are automatically switched. Switching positioning adopts a dual combination of mechanical and photoelectric limits to improve positioning accuracy.
• It supports the conversion of various hardness scales in real time and has the function of upper and lower limit settings.
• Real time saving of hardness test results, automatic calculation of maximum, minimum, mean, etc., with multiple folder selection, optional deletion and printing output.
• Built in thermal printer with fast printing speed, and equipped with USB interface for users to output the data.
