Abstract
An indentation type hardness tester applies a predetermined force to an indenter and the indenter produces an indentation on a test specimen, and then measures the shape and size of the indentation. The hardness tester has a tester body and different frames. The tester body has a cavity and a magnetic base. The user selects different frames based on measurement needs and installs the frame into the magnetic base of the tester body. The testing head is equipped with an optical imaging system, the front end of the testing head is equipped with a removable load cell, and the front end of the load cell is equipped with an indenter. The indenter, load cell and optical system are coaxially oriented. A motor moves the tester body to perform the indentation.
