Rockwell Hardness Tester TH300/320 Protrudent indenter

Rockwell method measures the permanent depth of indentation produced by a force. Press the indenter into the sample surface with the initial test force, and then apply the main test force. After remove the main test force, the depth of the indentation indicates the hardness. TH300/320 rockwell hardness tester is featured with protrudent indenter to test hard-to-reach places and automatic loading/unloading.
