Vickers Hardness Tester XHV-5/10/30/50

Main Features
This Digital Vickers Hardness Tester made with a unique and precise design in the fields of mechanics, optics and light source is able to produce a clearer indentation and hence a more precise measurement. By means of 10x lens, 20x lens or 20x lens and 40x lens, the tester has a wider measurement field and broader usage range. The set of lens (2 pieces lens ) can be selected according to the user’s requirement. With an automatically turning device for indenter and objectives ( the automatically turning turret ) , the operation has become easier; and with a thread interface, it can be linked to a digital camera and a CCD Vide-camrea as well as video measuring devices and indentation automatically meausring device without switching optical path. It is the first tester that adopted the touch and color LCD screen, thus making the operation more humanized. The tester has such features as the direct reading of the measurements, the easy change of the hardness scale, the reservation of the data, the priting and linkage with RS232 interface. By means of closed - circuit system for control , CPU controls testing force to load; dwell and unload, the sensor feedback information, therefore the lost of testing force value can be automatically compensated during testing and hence the testing force more accuracy. The instrument represents today’s world advanced level among the products of the same kind in China.

Usage Range

● Ferrous metals, non-ferrous metals, IC thin section, coating, ply-metals；

● Glass, ceramics, agate,precious stone, thin plastic sections,etc.  ● Hardness testing such as that on the depth and the trapezium of the carbonized layers and quenched layers.
