DHV-50 Vickers Hardness Tester is a new and high-tech product combining optical, mechanical and electronic techniques. With novel appearance, good reliability, operational functions and direct viewing.
Through handing menu keys, the equipment performs complete functions such as selecting Vickers or knoop hardness testing mode, adjusting the intensity of black light, displaying on LCD digital screen the dwell time, numbers of measurement, hardness value exchange,and setting YTD(year to date). Besides, the length of indentation diagonal line can be keyed on operating board, then directly readout the hardness value from the screen，which is free from checking the tables.

The instrument is suitable for testing Vickers hardness value of thin pieces, the parts after surface treating with permeating and coating, and it is also fit for measuring Knoop hardness value for crisp and hard material such as glass, ceramics, agate, man-made precious stone；therefore, it is an ideal hardness measuring equipment for the scientific research institutes, industrial enterprises and the metrological institutes using for studying and measuring.

Using scope:
Heat treated layer, carbonized layer, hardened hard layers, superficial coating, steels, non-ferrous metal, thin shaped components.
