210SCB-3000S digital display Brinell hardness machine is an optical, mechanical and electrical integrated product with precise mechanical structure. It adopts electric loading and unloading test force. The indentation can be directly measured on the instrument through the micrometer eyepiece. The measured indentation diameter can be input through the key to obtain the hardness value. The hardness value can display the indentation diameter on the LCD screen, and input the load holding time and the scale on the page.
