● iBrin-417L is a half automatic and intelligent Brinell hardness testing machine, it adopts the pressure sensor to replace the traditional quality weight, this innovative design makes the instrument more accurate;

● iBrin-417L selection of testing force and dwell time is controlled and monitored on the front panel, it is automatic during the process of loading, dwell and unloading;

● iBrin-417L adopts digital Brinell microscopes with adjustable LED illuminator, it doesn’t need the operator to read the detail length of indentation, it only needs operator to aim the D1, D2 diagonal of indentation and press the length key twice above the Microscope, then the built-in computer can compute the Brinell scale and display the final testing result on LCD display automatically;

● iBrin-417L doesn’t need the operator to read the detail diameter of indentation and check the Brinell testing table, it improves the testing speed and accuracy of hardness testing obviously.
