DHV-2011 Digital Micro-Vickers Hardness Tester

The DHV-2011 digital Micro-Vickers hardness tester adopts the precision machinery and photoelectrical computer software. It can be used for Vickers or Knoop hardness test. The operator can input the measured diagonal value into the integration computer, so as to calculate the hardness number. This sclerometer is suitable for testing metallic materials, including minor component, sheet, tinsel, wire, thin hardened layer, galvanized coating, etc. The hardness tester can also measure glass, jewelry, ceramics and other non-metallic materials. In particular, the hardness testing machine is capable of test the internal hardness of induction hardening or carburization materials, in line with metallic structure.
