Semi Automatic Micro Hardness Tester Vickers , Metal Hardness Testing Machine

Semi Automatic Micro Hardness Tester Vickers , Metal Hardness Testing Machine

VH-EM Vickers hardness tester adopts precise structural design, testing force changed from weight to sensor control, it makes the machine with simplicity structure and stable, accuracy force display. This series Vickers hardness tester is controlled by CPU on the whole testing procedure and adopts latest technology,
 
Such as high definition optical measurement system, photoelectricity sensing and cold lighting source. With the functions of inputting data through softkey, presetting testing loading time, choosing Knoop testing or Vickers testing, adjusting light intensity, it is also able to display the length of indentation, hardness value, holding time and count of test on the LCD. This series Vickers hardness tester could install CCD device, monitor device and camera head based on customer’s requirement.

Features:
● It 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.
● 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.
● It 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
● It 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.
● Hardness conversion among 17 hardness scales, and linking to PC in RS232 interface and cable
