Hardness Testing Machine

• The rigorous optical structure and high magnification make the observed indentation very clear.
• Objective and indenter are automatically shifted based on the selected scale, and then the hardness tester will perform the measuring and observing.
• The automatic lifting table uses precision structure for high stability and it will automatically rises when the test starts, and then return to the focusing position for measuring after the test force is loaded.
• This hardness tester adopts integrated design of tester and computer, using Windows 7 operating system.
• Built-in CCD camera and touch screen allows for preseting of dwell time of test force, adjusting the intensity of light source, displaying of indentation length, hardness vaule, test range, test number, etc.
• The software features function of calibration, allowing manual fine tuning and setting up of top and bottom limit for alarming, which ensures the measuring precision.
• Conversion scales allows selection for various scales of hardness.
• USB port, VGA interface and LAN interface are available for connecting to the internet and other devices for more optional functions.
• The main body is made of cast iron, achieving 99% rigidity and minimizing deformation. The tester’s housing has undergone a natural aging process for over six months, ensuring stable physical properties.
• Features a high-precision gravity sensing system combined with a gap-free ball screw, allowing for accurate 1:1 control of the test force. With a 0.03-grade force sensor, it ensures precise and consistent loading every time.
• The screw rod, equipped with imported NSK bearings from Japan and a ball screw, undergoes heat treatment to reach a hardness of 35-40HRC. This enhances the stability of test data at different heights.

XHBT-3000Z II Hardness tester is suitable for measuring cast iron, steel, nonferrous metals, soft alloys and non-metal materials like rigid plastics, bakelite, etc.
