Equipment Usage:

• 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, nitride and hardened layers of metals.
• It is also suitable to determine the Vickers hardness of micro and super thin parts.

Features:

• Made with a unique and precision design in the field of mechanics, optics and light source. Able to produce a clearer image of indentation and hence a more precise measurement.
• By means of a 10X objective and a 40X objective and a 10X microscope for measurement.
• It shows measuring method, the testing force value, the indentation length, hardness value, the dwell time of the testing force, as well as the number of measurement on the LCD screen.
• During the operation, put in the diagonal length with the keys on the keyboard, and the built-in calculator automatically calculates the hardness value and shows it on the LCD screen.
• The tester has a threaded interface that can be linked to the digital camera and CCD pickup camera.
• The light source of the tester is firstly and uniquely adopted cold light source, and hence its life can reach 100000 hours. The user also can select halogen lamp as light source according to their requirement.
• The CCD Automatically Image Measuring Device can be equipped on present tester according to user’s requirement. (optional)
• The LCD Video Measuring Device can be equipped on the present tester according to user’s requirement. (optional)
• According to user’s requirement, the tester also can measure Knoop hardness value after equipping a Knoop indenter.
