Repair, maintenance and calibration of Micro Vicker hardness tester
Hust Vietnam conducts repair of the Micro Vicker hardness tester at VSIP Industrial Park, Binh Duong province.
Device status:
The machine has been in operation for more than 10 years so it is relatively old. The lens system is dusty, resulting in very blurry images. The position of the lens system deviates from the tip of the stab, so it is very time-consuming to take the measurement.
The machine uses 110V current (according to Japanese standards), but the staff did not pay attention, plugged in the wrong voltage of 220V, causing the transformer to burn.
With professionalism and in-depth experience in the field of hardness measuring machines, HUST Vietnam engineers quickly identified the cause and promptly repaired it for customers.
