The Digital Micro Vickers Hardness Tester (Automatic Turret) is a high-performance measuring and testing instrument supplied by Mikrosize, a trusted provider of precision testing equipment. Designed to meet the rigorous demands of material hardness testing across various industries, this advanced instrument combines cutting-edge technology with user-friendly operation to deliver accurate and reliable results consistently.
As a leading measuring and testing instrument from Mikrosize, this digital micro Vickers hardness tester features several key attributes that distinguish it in the market. It employs a direct weight-adding mechanism for exceptional precision in test force application—a critical factor for consistent hardness measurements. The instrument also includes automatic data input, with hardness values clearly shown on a 5-inch LCD screen, and supports on-demand printing of test results via its built-in printer, streamlining data recording and documentation.
Equipped with a high-precision optical measurement system, this instrument ensures sharp, clear imaging for accurate indentation measurement. It utilizes the widely adopted ARM32 series microcontroller, offering fast computation and high data-processing accuracy for rapid and precise hardness value calculation. The worm gear and side handwheel lifting mechanism provides smooth and stable adjustment of the testing head, while the Z-type automatic turret enables one-button switching between the objective lens and indenter, reducing manual intervention and improving operational ease.
This Digital Micro Vickers Hardness Tester covers a comprehensive range of test forces, meeting both micro and standard Vickers testing requirements. Available forces include (0.098, 0.246, 0.49, 0.98, 1.96, 2.94, 4.90, 9.80) N, equivalent to (10, 25, 50, 100, 200, 300, 500, 1000) gf. Loading, holding, and unloading of the test force are fully automatic, with a programmable hold time from 5 to 60 seconds to accommodate different material testing needs. The automated process minimizes operator-induced errors, ensuring reliable and repeatable results.
In terms of measurement performance, the instrument offers a micrometer drum division of 0.025 μm and a hardness measurement range from 5 HV to 3000 HV, making it suitable for a wide variety of materials. It includes a precision coordinate test stage measuring 100 × 100 mm with 25 × 25 mm travel, enabling accurate specimen positioning and measurement of hardened layer depth and hardness gradient—essential for quality control in heat treatment processes.
To extend its functionality, Mikrosize offers optional accessories such as a video system and a CCD image processing system for enhanced visualization of indentations and microstructures. The built-in printer and RS232 data interface facilitate easy output, storage, and computer connectivity for further data analysis and management.
Compliant with GB/T4340.2, ISO6507-2, and ASTM E92 standards, this instrument guarantees accurate, reliable, and internationally recognized test results. It measures 530 × 290 × 490 mm and weighs 40 kg, offering a compact yet stable footprint suitable for laboratory environments.
The application range of this digital micro Vickers hardness tester is broad. It is suitable for testing ferrous metals, non-ferrous metals, IC substrates, surface coatings, and laminated metals. It can also be used on brittle materials such as glass, ceramics, agate, and gemstones. Furthermore, it is widely employed in measuring the depth and gradient of carburized and quenched layers, making it an essential tool in industries including machinery manufacturing, automotive, aerospace, electronics, and materials research.
