The Vexus SHB-3000N is a mechanical and electrical integration product of precise mechanical structure and microcomputer controlled closed-loop system.Loading and unloading test force electrically instead of using the weight. The test force is fed back by a 0.5 ‰ precision pressure sensor. The CPU can control and automatically compensate the test force lost during the test. The indentation can be directly measured on the instrument through a micrometer eyepiece.The test force, indentation length, load holding time, measurement times, conversion scale, date and time can be displayed more intuitively on the large screen. Only measuring the indentation and pressing the eyepiece button,then the hardness value can be calculated automatically and displayed on the screen. The data results can be saved and viewed, or output through a built-in printer.
