THV-2000 Micro Vickers Hardness Tester

THV-2000 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 .Besides, it has such functions as registering the date, and measuring results , treating the data , outputting the information with the printer, and carrying out the operations of directly showing the measure number , exchanging the scales among the 17 scales , putting the data into the bank and linking to RS232 interface and to the digital camera and CCD pickup camera with a threaded interface . The instrument is, therefore, quite advanced and 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.
