The HVS Series of Digital Vickers Hardness Tester made with a unique precision design in the field of optics, mechanics, and light sources. The HVS is able to produce a clearer indentation and thus provides a greater accuracy in measurement. The 5Kg tester matches the 20* and 40* objectives and the 10 Kg matches the 10* and 40* objectives, and the 10Kg matches the 10* and 40* objectives. The 30kg and 50kg matches with 10* and 20* objectives. All of the stated objectives can be used for the measurement and the enlargement of the measuring range and a wider usage field. The HVS comes with an digital microscope, test force, display testing method indentation length, hardness valve, dwell time of test force along with the length of measuring times. There is also a unique interface that allows for linkage of video measurement device and indentation automatically without having to change the optical path.
