Fully Automatic Brinell Hardness Tester

XHBT-3000Z III fully automatic Brinell hardness tester adopts precise structure design, the load of test force is controlled by the sensor, which makes the whole structure compact and loading of test force stable and exact. With built-in touch screen and micro computer, it makes the parameter setting and results show directly with easy operation, it also avoids the stimulation and visual fatigue of the light source of the eyepiece, and reduces the measuring error. After select the scale, the instrument will automatically select the indenter and objective, the test table rises automatically and then back to the focusing position after touching the indenter. Then it automatically loads, dwells, unloads, and switches to the objective, with clear indentation display and automatic measurement, achieving one click automation of Brinell measurement.

• 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 10 level of test force, 13 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, with automatic shifting the instrument will automatically select the corresponding indenter and objective for measurement. Switching positioning adopts a dual combination of mechanical and photoelectric limits to improve positioning accuracy.
• The automatic lifting test table adopts precise structure with high stability, and it can also quickly rise or descend with jog operation.
• It adopts the integrated design of hardness tester and micro computer, and it has all functions of computer with Windows operating system.
• With CCD image measuring system, touch screen operating and displaying, real time saving and list display of indentation length and hardness value data results, capable of generating WORD or EXCEL reports.
• With USB, VGA, LAN ports, it can connect to the internet and other devices for more optional functions.

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.

• Basic function: include all functions of image processing and measurement system, such as image capture, calibration, image processing, geometric measurement, annotation, photo album management and fixed times print etc.
• Automatic measurement: Automatically capture the indentation and measure the diameter and calculate the corresponding value of Brinell hardness.
• Hardness conversion: The system can convert the measured Brinell hardness value HBW to other hardness value such as HV, HR etc.
• Data statistics: The system can automatically calculate the average value, variance and other statistical value of the hardness.
• Standard exceeding alarm: Automatic mark the abnormal value, when the hardness exceeds the specified value, it automatically alarms.
• Test report: Automatically generate the report of WORD or EXCEL format.
• Easy to use: One key operation for automatic measurement. If need manual measurement or modify the results, just drag the mouse.
• Strong noise resistance: The advanced and reliable image recognition technology can handle the indentation recognition on the surface of the complex sample. Two automatic measurement modes to handle extreme situations.
• Automatic calibration: The system has provided a calibration function, convenient for the indentation size measurement and may calibrate at any time. With a calibration grid, the system can automatically implement full calibration for calibration grid intersection points to eliminate measurement error caused by lens distortion.
