Product Feature:
Digital display Vickers series hardness tester is a high-tech product of opto-mechatronics. The display screen uses a large LCD screen. It is novel in shape, beautiful, and has good intuitiveness, operability and reliability. It is an ideal product for testing Vickers hardness. The machine uses an automatic switching device for the changeover between the indenter and the objective. The hardness tester adopts precise structural design in machinery, high magnification objective lens and digital micrometer eyepiece in optics, and closed-loop electronic loading control system, which improves the accuracy of test force and shows good repeatability and stability. The operation is input by the touch key on the panel, which can preset the test force and load time, adjust the strength of the measuring light source, select Vickers or Knoop test mode, hardness conversion scale, storage, etc. And can display on the screen measuring indentation length, hardness value, measurement times and years, months, days and time, test results and data processing, and through the printer output, but also through the RS232 interface and computer connection is widely used in industrial and mining enterprises and colleges and universities laboratory.
Application:
Suitable for quenching, quenching and tempering, annealing, chilled castings, malleable castings, hard alloy steel, aluminum alloy, copper alloy, bearing steel and other hardness determination.
