Usage:

This tester is a new type of product which is equipped with new features such as RS232 interface, automatic turret, high level LCD display etc. It is specially suited for measuring the Microhardness of thin, small metal test pieces and the brittle materials.

Features:

• Automatic turret switching between penetrator and objective lens.
• Frictionless loading shaft, high precision testing force.
• Automatic testing process, no human operating error.
• Precision conforms to GB/T 4340.2, ISO 6507-2 and ASTM E384.
• It can be used to determine the Vickers hardness of steel, non-ferrous metals, ceramics, treated layers of metal surface, and the hardness grads of carburized, nitrided and hardened layers of metals. It is also suitable to determine the Vickers hardness of micro and super thin parts.
