DHV-1000
Description:
Main Features
DHV-1000 Micro Vickers Hardness Tester made with a unique and precise design in the field of mechanics ,optics and light source is able to produce a clearer indentation and hence a more precise measurement. By means of a 20 × lens and a 40 × lens the tester has a wider measurement field and a broader usage range. Equipped with a digital microscope, it shows the measuring methods, the test force, the indentation length, the hardness value, the dwell time of the test force as well as the number of the measurements —— all shown on its LCD screen. What is more, it is equipped with an interface linked to a digital camera and a CCD video—camera, and is, therefore, a representative of the products of the same kind in the country.
Usage Range:
Ferrous metals, non-ferrous metals, IC thin sections, coatings, ply-metals;
Glass, ceramics, agate, precious stones;
Hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.
