Vicker’s Hardness Tester is a testing instrument to measure the hardness value of all kinds of metals according to Vicker’s hardness principle ASTM E92 and ISO 6507. They are widely used in metallurgy, forging, casting, hardness steel and nonferrous metals industries, as well as in the laboratories, universities, college and scientific research institutes. HVS-5/10/30/50 Digital Vickers Hardness Tester - Unique and precision design, can produce clearer indentation. - Wide measurement field, broader usage range. Can equipped with 10X and 20X lens or 20X and 40X lens and 2 pieces lens can be selected according to user’s requirement. - Equipped with digital microscope; LCD screen can directly show measurement methods, test force, indentation length, hardness value, dwell time of test force and the number of measurement. - With optional linking with video measuring device and indentation automatically measuring device without changing optical path. - Adopting cold-circuit lamp, the life of light source can reach100, 000 hours. - Closed-loop control system. Microchip controls testing force to load, dwell and unload; the sensor feedback real load, the lost of testing force value can be automatically adjust during testing and warrant the testing force more accurate.
