Features:
The MHV-30/MHV-30Z digital Vickers hardness tester is a high-tech product that integrates optics, mechanics, and electronics. The instrument adopts a closed-loop loading control system, which improves the accuracy of test force, and has good repeatability and stability of indication. Equipped with a digital micrometer eyepiece, there is no need to check the gauge or input the diagonal of the indentation. It can display the test force, indentation length, holding time, measurement times, conversion scale, date and time more intuitively on the large screen. When operating, simply press the eyepiece button to automatically calculate the hardness value and display it on the screen. The data results can be saved and viewed through a table, or output through a built-in printer, and equipped with an RS232 interface for users to connect to a computer for output. Optional LCD video measurement device and CCD image automatic measurement system.
Application scope:
Black metal, non-ferrous metal, IC sheet, surface coating, laminated metal; Glass, ceramics, agate, gemstones, thin plastics, etc; Hardness testing of depth and gradient of carbonization layer and quenching hardening layer.
