NHVS-1000 Digital Vickers Hardness Tester - Precision & Durability

NHVS-1000 and NHVS-1000Z type automatic turret digital micro vickers hardness tester is a high-tech product of optical and mechanical integration. The instrument is novel and beautiful, and it has good reliability, operability and intuitiveness. It is an upgraded product for micro vickers hardness testers. The machine adopts computer software control, a high-resolution optical measurement system, photoelectric sensors and other technologies to realize the automatic switching between the measuring device and the indenter. Through software input, the intensity of the light source can be automatically adjusted, and the Vickers and Knoop test methods, retention time, file number and storage can be selected. It provides a variety of hardness value conversion tables for reference. On the large LCD screen, it can display the test method, test force, measured indentation length, hardness value, test force holding time, measurement times, and the year, month, date can be input, as well as test results and data processing. The results can be output through the printer.

    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.
