Product Description
DHR-45D Digital Superficial Rockwell Hardness Tester is an advanced model among superficial rockwell hardness testing equipment,it adopts large LCD digital screen as well as menu structure to display hardness value,which is reliable and stable in performance.
Through large LCD digital screen operation,you can freely select different available scales of superficial Rockwell hardness,and then make test;moreover,different hardness values can be exchanged;you can also save the testing result and print it out if necessary;it has function of RS232 super terminal setting;optional data processing software can also help you to deal with testing result.
Using scope:
Surface hardened steel, copper, aluminum alloy sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface heat treating and chemical treating materials, etc.
