AUTO TURRET DIGITAL DISPLAY VICKERS HARDNESS TESTER
Feature & Use
Automatic turret shifting between indenter and objective lens.
Large LCD screen display, easy and convenient operation.
Electric loading without weights, closed loop control.
Digital measurement, measured hardness value will be displayed on LCD directly.
High quality integral casting cast iron machine body with automotive paint treatment process, the appearance is smooth and beautiful.
The hardness scale, test force, indenter type, holding time and the conversion unit can be displayed on screen and set.
HD measurement and observation – dual objective lens combination, combined with the built-in length encoder HD micrometer eyepiece, to achieve indentation diagonal one-key measurement, greatly reduce the manual interference and reading error.
Convenient control system can automatically convert the unit of full hardness scales.
The maximum and minimum hardness values can be set, when the test value exceeds the set range, an alarm sound will be issued.
The hardness value can be corrected within a certain range by standard scale.
With the database function, the testing result can be saved automatically up to 200 data.
CCD image measuring system is optional.
Equipped with wireless blue-tooth printer, the data can be output through RS232 or USB interface.
Precision conforms to GB/T4340.2 ISO6507-2 and us ASTM E92.
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.
