Professional Automatic Digital Vickers Hardness Tester
The TH721Z Digital Vickers Hardness Tester is a premium automatic digital Vickers hardness tester designed for precise hardness testing of metals, coatings, thin sections, ceramics, glass, electronic components, and heat-treated materials. Combining advanced optical, mechanical, and electronic technologies with a high-precision load cell control system, automatic objective switching, and a digital measuring eyepiece, the TH721Z delivers highly accurate, repeatable, and efficient Vickers hardness testing for laboratories, research institutes, universities, and industrial quality control.
The TH721Z Digital Vickers Hardness Tester utilises a closed-loop load cell control system that significantly improves test force accuracy, repeatability, and long-term measurement stability. Automatic loading, dwell, unloading, and automatic switching between the objective lens and indenter streamline the testing process while ensuring consistent measurement conditions. The digital measuring eyepiece automatically calculates and displays the hardness value after indentation measurement, eliminating manual calculations and greatly reducing operator error.
Designed for High-Efficiency Vickers Hardness Testing
The integrated digital measuring eyepiece displays indentation length, test force, dwell time, hardness value, conversion scale, test number, date, and time directly on the screen for intuitive operation. The high-quality optical system provides 100× and 200× total magnification with measurement resolutions down to 0.13 μm, enabling highly accurate indentation measurement across a broad range of engineering materials.
The TH721Z supports Vickers test forces from 0.5 kgf to 50 kgf, making it suitable for testing ferrous metals, non-ferrous metals, thin coatings, plated materials, ceramics, glass, gemstones, plastics, integrated circuit cross-sections, carburised layers, and hardened surfaces. Built-in printing and RS232 connectivity simplify data management, while optional LCD video measuring equipment and a CCD automatic image measuring system further enhance testing efficiency through automated indentation analysis. Complying with ISO 6507, ASTM E384, and JIS Z2244 standards, the TH721Z provides dependable Vickers hardness testing for laboratories, production facilities, and quality assurance applications.
