Two Indenters Vickers Hardness Tester

Built with a new aluminum alloy die-casting process, the QHVT-10ZD/50ZD digital Vickers and Knoop hardness tester boasts a sturdy, stable housing with a sleek, modern design. Its direct drive loading mechanism ensures consistent force application and high testing throughput. The unit comes with two indenters and four objectives that feature automatic recognition and switching, making it adaptable to a variety of testing scenarios.

A digital eyepiece works in conjunction with the touch screen to clearly display test force, indentation length, dwell time, conversion scale, date, and time. Operation is straightforward: after measuring the indentation, simply press the eyepiece button, and the hardness value is automatically calculated and shown on the screen.

• Crafted with a new aluminum alloy die-casting process, the main body is sturdy, stable, and visually appealing.
• Crafted from a specialized material and heat-treated to 35–40HRC, the lifting screw offers exceptional wear resistance. The worm gear and worm structure further ensures smooth, stable lifting operation.
• The closed-loop load cell loading system, combined with a direct-drive motor that applies test force vertically, provides exceptionally stable performance.
• The turret's rapid rotation significantly enhances overall testing productivity.
• The loading and turret motors are both imported, ensuring superior build quality, low noise levels, and reliable stability.
• The modular cover design of the machine body ensures hassle-free maintenance.
• With a six-station turret that holds Vickers and Knoop dual indenters and 5X/10X/20X/40X objectives, the instrument automatically identifies and switches between them for seamless operation.
• The turret switching system integrates mechanical and photoelectric limits, providing superior positioning accuracy to maintain precise six-point-one-center alignment.
• The LED light source delivers superior durability for prolonged use.
• The 8-inch HD color touch screen features an adjustable angle, making operation more comfortable and user-friendly.
• With Vickers and Knoop testing modes built in, the system allows for real-time conversion between various hardness scales and convenient on-demand switching.
• The system allows for upper and lower limit configuration, delivering clear prompts whenever test results exceed the specified tolerance.
• The instrument offers real-time storage of hardness test results, with functionality for data classification and selective deletion. Automatic calculation of maximum, minimum, and average values is provided. Furthermore, an RS232 interface is included to facilitate PC connectivity for data output.

This equipment is suitable for a broad spectrum of materials: ferrous and non-ferrous metals, IC thin sections, coatings, ply-metals, glass, ceramics, agate, precious stones, and thin plastic sections. It is also applicable for hardness testing of carbonized layers and quench-hardened layers, with capabilities to evaluate both depth and trapezoidal profiles.
