·HV-50AC is a half automatic and intelligent Vickers hardness testing machine , it adopts the close- loop force sensor to replace the traditional quality weight, this innovate design   makes the instrument more accurate.

·HV-50AC 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.

· HV-50AC adopts digital microscopes with adjustable LED illuminator, it doesn't need the operator to read the detail length of indention ,it only needs the operator to aim the D1,D2 diameter of indention and press the length key twice, then the built-in computer can compute the Vickers scale

·HV-50AC equipped with a large LCD screen, The operation is more directly and clearly.

·HV-50AC doesn't need the operator to read the detail diameter of indention and check the Vickers testing table, it improves the speed and accuracy of hardness testing obviously.

·HV-50AC hardness conversion among 17 hardness scales, and linking to PC in RS232 interface and cable.
