DHV-50D Digital Vickers Hardness Tester equips with large LCD displaying screen, it is a new and high-tech product combining optical, mechanical and electronic techniques. With novel appearance, good reliability, operational functions and direct viewing, it is a new type Vickers and Knoop hardness measuring equipment, which adopts precise mechanical, optical and electronic techniques.

Additionally, he equipment is adopted technology of computer making programs with software, high amplification optical measuring system and photoelectric sensor. Through handing menu keys, the equipment perform 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, and setting YTD(year to date).

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.
