These two indenters adopt the independent alignment device which ensures that Vickers and Knoop indentation are at the same center position.
--Show the test mode, test force, indentation length, dwell time, test times, conversion scale and date & time directly on the large screen without checking the conversion table or inputting the indentation diagonal.
--Get the hardness value automatically and show it on the screen by pressing the confirmation button on eyepiece after measuring the indentation length.
--Up & Down Limit Alarm
--Test results can be saved for checking.
--Built-in printer for test results printout
