NHV-1000 Digital Micro Vickers Hardness Tester for Precision Testing

Micro Vickers Hardness Tester is a high-tech product combining optic, mechanic and electronic techniques. It is suitable for measuring the hardness of thin materials and tiny parts, such as the parts in clocks, instruments and meters, as well as the hardness and thickness of surface coatings, carburized layers and nitrided layers. It is an important means for inspecting product quality and formulating reasonable processing techniques. In particular, it will become one of the commonly used testing methods in metallography and materials science. The HV-1000 microhardness tester and the HV-1000Z automatic turret microhardness tester can meet the basic Vickers hardness testing requirements, and the upgraded control system can provide more measurement data and more accurate control.

Product Detail

Features

● Optical system's outstanding features: The optical system designed by senior optical engineers not only has clear images but can also be used as a simple microscope. The brightness is adjustable, providing a comfortable visual experience and lessening fatigue during long-term operation.

● Advantages of the industrial display screen: The industrial display screen can intuitively show hardness values, hardness conversions, test methods, test forces, holding times, measurement numbers, and the test process is clear and straightforward.

● Highlights of the cast aluminum shell: The cast aluminum shell is formed in one piece, with a stable structure that does not deform. It has a high-grade pure white automotive paint finish, strong scratch resistance, and remains shiny and new after many years of use.
