Brinell Hardness Tester VB62.5
Brief Introduction:
VB-62.5 digital low-load Brinell hardness tester is a high-tech
electro-mechanical and electromechanical product. The machine is
novel in design, with good reliability, operability and intuition.
VB-62.5 adopts digital Brinell microscopes with adjustable LED
illuminator, doesn’t need the operator to read the detail length of
indentation, just 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;
Features:
VB-62.5 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;
VB-62.5 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;
VB-62.5 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;
VB-62.5 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.
